How do I set up a custom validation formula to prevent duplicate enties?
For example I I've already enter the song name 19 and Paul Hardcastle (BandName), how do I set it up where I can not enter that combination again on a row?
I was wanting to use a custom CountIF function but I could not get it to work.
A
B
Song
BandName
19

New here, I wanna do a "Prevent Duplicate Entries" into my column i try the following: http://www.mrexcel.com/articles/prev...duplicates.php
http://www.theexceladdict.com/_t/t040818.htm
They all work well but if I'm using copy and paste It doesn't work! why is tat so?
Second issue will be i'm wanna do prevent duplication for the whole column not just one cell.
I've got this code for prevent duplicate entries, But I wondering if it's possible to add a copy rows to it? For Example
Columns C
ItemID ItemName
11 QWE
22 ASD
33 ZXC
So now I enter 22 in ItemID for this working code it will pop up a MsgBox saying Aready exist, Is it possible to add a code so that it will copy the existing copy and paste into the active row?
Private Sub Worksheet_Change(ByVal Target As Range)
Dim r As Range
Dim ans As String
Const myCol As Long = 3
If Intersect(Target, Columns(myCol)) Is Nothing Then Exit Sub
Application.EnableEvents = False.........

myCount = 0
If Range("B" & myRow).Value <> "" Then myCount = myCount + 1
If Range("C" & myRow).Value <> "" Then myCount = myCount + 1
If Range("D" & myRow).Value <> "" Then myCount = myCount + 1
If Range("E" & myRow).Value <> "" Then myCount = myCount + 1
If myCount > 1 Then....................
The above code pops up the message box when a second entry is made within the specified range, but OK button does not function, contents are not cleared, and Excel locks up.
I tried to solve above problem using Data Validation formula. Data validation does not work if somebody copy paste the duplicate values,it works when somebody types duplicate values in next column. So if I want to enter lot of urls to a column then it is completely impossible to type so must have to copy paste from the browser. I have attached a sample sheet, howl to solve this problem either using formula or using Data validation in sample 1 and sample 2 respectively.

View 9 Replies View RelatedI am looking for either vba or excel method to prevent duplicate entries across multiple columns. The data validation only works when it is input manually by the user and not when it is generated by the formula
What i am trying to do ( assuming " | " are column dividers and each new line is a row)
abc | 2 | bac | 3 | cab | 4
bac | 3 | abc | 2 | cab | 4
abc | 2 | bac | 3 | cab | 4
I have a spreadsheet that needs to have a validation drop down list in three cells in every row (D, E, F). There are three items in the list, say, "One", "Two" and "Three".
My only problem is that there can only be one entry of "One" in each row.
I am in need of 2 validation macros (formulas) to enter into the validation criteria formula box when creating a custom validation.
1. A formula that will generate an error if there is a space in the text entry. Example:060107_Halo3CG prev.mpg would be an invalid entry due to the space after CG.
2. The same formula as above but this one also needs a 50 character limit added to the criteria.
I am trying to create a column to match duplicate information, primarily numbers, so I can delete the duplicate information. Using the Find option is too time consuming. I am pasteing the new info above the previous weeks info. Some years ago I used a formula that would "Match" a range and I believe it would copy the duplicate in the empty column but it's been so long I am not certain nor do I remeber the formula. I've tried using the filter feature and looked at previous post but I am not familiar enough to know how to decipher the info given.
View 9 Replies View RelatedI need a formula (I'm not sure if its possible without using VB which I have found on another thread) that I can 'drag' down to the cell Bx (where x is variable) to extract unique entries in a list of values and then display them in a shorter, more concise list - like the 'Pick From List' function does but actually display these values in seperately in a column of cells.
Hope this is making sense.
So (hopefully) to elaborate:
A1:Ax = The list of values containing duplicates
B1:Bx = The list of only unique values from column A
Using frequency in a data validation formula for ensuring unique entries.
Currently I use COUNTIF($B$2:$B$244,B2)
I require a custom data validation formula to limit cell value to maximum of 4 decimal places.
0.0001 ok
0.02 ok
0.3 ok
0.12345 fail
0.123456 fail etc
I have this excel file with some functions inside a Pivot Table, which use a year value as filter (the value comes from a report filter field) and data from a different spreadsheet to calculate a percentile value ... I created custom functions to replace the excel functions, passing the values as parameters.. The problem is now that when we refresh the connection (Refresh All button under DATA tab) the cells that contain the values returned by the custom function lose those values (go blank) In order to get the values I need to select the filter value again, while when I was using the normal PERCENTILE function the values would always refresh normally
Now... I think the problem might be related to the fact that the spreadsheet in question calls 5 different custom functions at the same time.... and, those 5 function call another at least two more helper functions... so, maybe this recurrence in calling the functions is causing the thing to break up
Is there a way I can prevent this from happening? Maybe put some flag or something that will cause the functions to be executed one by one, and not all at the same time?
I added a menu command button to a toolbar in a specific workbook. The macro is housed only in that workbook and the macro needs to run on every worksheet in the workbook. However, the button also appears on EVERY Excel workbook that I open when it should not. How can I create a menu command that only appears in the workbook that contains the macro?

I have a piece of code that hides unneeded rows, it does work but it is very slow.
This is in the worksheet part of the project. My problem is as it runs it "jumps" in to a function I have in a module that counts continuous rows. I would like to know why it is doing this and what I need to do to stop it? I have another piece of code that is structered exactly the same that hides unneeded columns and I do not have any problems with that. I know both pieces of code are dealing with rows and I think this is part of the problem but I can not see any reason why the first bit would call the second bit?
Dim C
With Worksheets("CEN OAS"). Range("D5:D378")
.EntireRow.Hidden = False
End With
For Each C In Worksheets("CEN OAS").Range("D5:D378")
If C.Value = "" Then
C.EntireRow.Hidden = True
End If
Next C

How prevent duplicate when entry from list?

I have one main tab which I pull data from other various tabs. To match data the data, I create a "common unique ID", in other words I create a column on each tab and connect various cells with the ampersand.
So in each of the various tabs (and the main tab), I'll have a column with something like =A2&B2&C3
If the "unique ID" matches between the tabs it will pull back the desired phrase, or it will be left blank. (Just using an =IF(ISNA) formula)
If you have followed so far, on my main tab, I have a column for each of the various tabs. The information I am trying to match could be on any of the tabs, so I need a column using an =IF(ISNA) formula to attempt to match each tab. So, on the main tab, there are several columns which might have the phrase I am looking for. I use another ampersand function to add those columns. My problem is that occaisionally, what I am looking for is on multiple tabs. So, if I am normally pulling the phrase "Pending Loans Report" when a match is made, if it is on two tabs, the cell will add it twice "Pending Loans ReportPending Loans Report"
I realize this is confusing, so I attached a spreadsheet. The "main" tab I was referring to is sheet1. I really simplified it down to post here, but I think the main idea of my problem is still evident. The problem is line 15. Note how column M has "Pending Loans ReportPending Loans Report" - I'd like it to only say this phrase once. The macro pastes special values at the end, but I've highlighted some cells in red which show the formulas I used for that column. Columns N, O, P, Q, etc. all have virtually the same formula.
I have a worksheet that you can enter in
Forename, Surname, Area, D.O.B
This has a macro assigned that copies the data and pastes it into another worksheet at the next available row.
Now this works fine, but I want to be able to identify if the data already exists in the other worksheet then prevent it from being pasted and give an error message that the person already exists in the database.
Is this possible?
I have a huge worksheet with 26 columns and 1200 rows. This worksheet is updated by 4 people everyday. Column C, H, N & R are updated daily by these 4 people so these are dynamic columns so to speak. I would like to have a VBA that informs that particular individual when he enters a duplicate data, maybe a popup saying duplicate entry.
View 9 Replies View RelatedI have a entry form in which i want to register customers. the first field is the customer number (which is unique(created by me) for every customer). This is TextBox 1 in the document. I would like to search for duplicates in worksheet 2, collumn A, when pressing "enter" to move from TextBox 1 to TextBox 2. A search for duplicates should start and a message should appear " duplicate found" if found, otherwise continue to TextBox 2 for further entry of information.
Please see my attached document for clarification.
I have a created recording sheet (attached) for the purpose of recording moths. I send this sheet out to those recorders who live in my county and at the end of the year they send the filled in sheet back to me. Over time I have put safeguards onto the sheet to ensure that I get the cleanest data returned to me. However, there is still one area which is giving me problems - users entering duplicate records.
Some formula which will stop recorders from entering those duplicate records. There are many columns on the sheet which recorders have to fill in with information, but as far as the duplicate records are concerned it is where the same information is entered into columns C, F and J that I'm having a problem with. It would be great if, when the same information was entered in these columns that the affected cells were highlighted in some way and if an error message appeared saying 'Duplicate record, either delete or alter grid reference'
I have entered two test duplicate record on the 'macro moths' sheet of the attached file : Test Recording sheet.xls
I am working pivot tables off of one large excel spreadsheet for my data. I have multiple pivot tables on each of 5 worksheets. The problem is this. Every other week I am sent an updated spreadsheet with the same column names each week which I then copy and paste it into the spreadsheet of the last one. When I refresh the pivot tables, I end up with duplicate field sets. For example, on column in the original data sheet is gender. On the first sheet I went through and renamed the "M"'s and "F"s to be "Male" and "Female" so that it is better looking when printed. Now when i get the new information and copy and paste it to rplace the old, and refresh the pivot tables, I end up with "Male" "Female" AND "M" "F". Now the "Male" and "Female" fields are empty and the "M" and "F" fields have the information. Is this a result of me renaming the fields?

That link worked for me but there's a problem with it, it does not work if a table has different types of validations.
I am trying to secure a worksheet using data validation. I want to prevent users pasting over data validation fields, however I want to allow users to be able to still use the copy/paste feature as long as the data is valid.
Attached is a sample that I found on the forums. The current code does not allow any paste functionality.
