# Data Validation With Negative Numbers

Jun 29, 2007
I want to use Data Validation on a cell (H1) to only allow the value entered to be values between values in E1 and D1. E1 is a negative number.I tried naming E1 & D1 as a range (valid) and then did custom validation formula is =valid, but that allows me to put in anything.

I have created a template using data validations. I have a drop down in column O, which you can choose from Credit or Charge. In column V, I want:

- If selected Credit in column O, only negative numbers allowed in column V

- If selected Charge in column O, only positive numbers allowed in column V

I have a large dataset (24000 rows) that requires me to multiply two different columns of integers. In some cases, the two integers are both negative and multiplying them results in a product that is positive. I actually need that product to be negative rather than positive. I can't quite seem to figure out the best way to accomplish this.

I have data that comes from a subsytem that places the negative sign at the right of the number, so it is recognized as text. I can get around this using find and replace and then a second step to multiply that by -1, but is there a formula that can do this for me?

I was trying if(right(A1,1)="-",TBD,A1)

Abc500

abc-500

bbb300

bbb250

cac100

cac-100

ddd200

ddd300

fff-500

I want to be able to highlight data in column B where amount is identical (ignore negative sign) only where data in column A is identical.

In this particular case it should highlight 500,-500 where data in column A = ABC & also 100,-100 where data in column A =CAC.

Ive attached a spreadsheet showing what im trying to achieve. basically i have a scheduling objective, in which only a few slots (AA, BB, CC) are available. so the starting availability is fixed. for this example assume the starting values are 6,7, and 8 respectively. as 'bookings' are entered, im using the value of -1 against A, B, or C respectively, to indicate that AA, BB, or CC should be decreased by 1 unit of availability.

im trying to incorporate the subtraction within a pivot table. as you can see i am way off. the hypothetical formula logic that im trying to implement within the PivotTable would look something like this:

for A,B or C, sum all (-1) values for each instance of Date and Stage... this will give total bookings

add this total value to the starting values of AA, BB, CC respectively to get the new availability

how can I set a cell so that you can only type in 1 , 2 , 3, 4, 5

I know I can use the validation but people can just copy a cell and paste it over.

The numbers will be both negative and positive just need to catch characters.

So:

2500 is okay

-15 is okay

is not okay.

I currently have cell B3 in a worksheet - able to except 2 data entries.

The user should enter either OPQ or BOT followed by numbers. How do i ensure that they only enter OPQ (O - Letter Not Number) followed by numbers, or BOT (O - Letter Not Number) followed by numbers.

i.e. OPQ87654321 NOT 0PQ87654321 or BOT12345678 NOT B0T12345678. The information has to be entered manually and not via drop down list as each number is unique to the OPQ or BOT.

Is it possible to force a cell entry (using Data Validation) to either a whole number or a value? In other words, I would like the data in a cell to be either a whole number between 10,000 and 20,000 or "N/A". I can do it with VBA, but Data Validation (if it's possible) would be better.

I am looking for a solution for my problem: I work for a bus company, I need a spreadsheet where I will record the bus numbers into a sheet but I only want to be able to add the number once ie. error if duplicate bus entered. Also the numbers will change from time to time, old buses sold when new ones arrive. I have the following code that someone helped me with wich works fine provided you don't have to change the numbers.

=And(Or(And(E42>=121,E42<=125),And(E42>=149,E42<=156),And(E42>=320,E42<=363),And(E42>=700,E42<=799),And(E42>=800,E42<=991)), COUNTIF($B$3:$E$46,E42)<2)

to validate a cell for the following customer format, but cant get it to work:

XX00000

Where XX is any combination of letters (upper or lowercase) and

00000 is a combination of any 5 numbers.

It must always be in this format, with this number of digits in total (2 letters followed by 5 numbers)

Usually this question is asked the other way around, but I have a somewhat unique problem. A certain website gives out tables filled with numbers. Positive numbers show in black font and negative numbers show in red font, but unfortunately, negative numbers do not include the minus sign -- the font is red and that's it!

I need a macro (or any other solution) that will turn the red font numbers to negative ones and would possibly format the cell to show negative numbers in red (I guess the last part is easier). The main problem is searching for the red font numbers and turning them negative.

I am looking for a way to define a 'Data Validated' Cell to hold a List of Dynamic Sequential Numbers - from 1 to the Value of cell A4. For example:

If cell A4 has a value of 5 the 'Data Validated' List will be 1,2,3,4,5

I have tried to 'name' the Array-Formula {=ROW(INDIRECT("1:"&A4))} and put the 'name' as the List source but without success.

I am using Excel 07 with Vista, and creating a spreadsheet in which users will be inputting a record into every row.

There is a row that requires a number to be entered, where some of the numbers will begin with 0 or 00 or even 0000. I want to make sure no-one incorrectly enters a letter, however with data validation set to whole numbers, it formats the cell to change an entry of "005667" into just "5667". There is no set length for the field.

The only way to have "005667" is the change the column to text, but then obviously that defeats the whole purpose!

How can I get the sum of a range excluding any negative numbers?

I've thought about using a new column and using if statement to separate but it would be easier if i could use the same column.

I'm trying to sum negative numbers using the following formula, however for some reason it's not working in the way that it would if I flipped the < to a > sign.

=SUMPRODUCT((Data!$AB$10:$AB$3222=$C$58)*(Data!$L$10:$L$3222=D57)*(Data!$W$10:$W$3222

I have a very simple formula which is basically one cell minus another "=A1-B1".

When the values are equal, the cell this formula is in will display a zero. However, when the subtracted figure is greater than the first figure, i will then get a minus figure E.g. 10-11 = -1.

How can i make it that when the formula result is less than zero (i.e. a minus number) the figure displayed stays at zero but still using the minus funciton? Basically once it hits zero i need it to stop subtracting. This may be really simple but i cant figure it out.

I want to key-in positive numbers, which I really want Excel to interpret as being NEGATIVE numbers. In other words, I want to avoid repeatedly striking the MINUS key. How do I:

Format these Data-Entry cells to this?

Format these Data-Entry cells to return RED displays?

I'm using Excel 2000

I have constructed an inventory formula, subtracting Current Inventory (CI) from Required Inventory (RI), to generate a number of how many new products must be Ordered: RI-CI=O. The problem is that if CI exceeds RI, I get a negative number for "O".

Question: How can I structure the formula to give a zero for any sum less than 1?

I understand how to only sum negative numbers but my problem is pulling only certain ones from a list. I have tried numerous IF and SUMIF statments with no solutions. I have attached a worksheet showing what I am trying to do.

I used this code to extract the value on the text: "11/09/09 backyard $400"

=IF(ISNUMBER(SEARCH("back",A4)),RIGHT(A4,LEN(A4)-FIND("$",A4))+0,"")

and return "400" but i've encountered a value which is negative (could be

-$400, or ($400); and i got an error of #value, could anyone resolve this problem?

IF formula

=IF(D9="","",IF(AND(G9>0,G10>0),"",IF(G9>=G10,G9,G10))+IF(E10=0,"",E10))

G9 and G10 can be positive or negative. If G9 or G10 is a negative number,

I want the greater of the two to be used and then to be added to E10. But

right now, Excel is saying -20 (which is G10) is greater than zero. I'm

getting a VALUE error.

I have been working on an excel sheet:

I am working with stock options. Therefore I must subtract the current stock price Cell C2, which has a value of 23 with the Options price which is D9, has a value of 34.79 then muliply it with the shares which is cell F9 which is 4000. So the formula that i have is (C2-D9)*F9 that gives me the sum which resides in cell I9(total outstanding profit).......This turns out to be a negative number. I want to make it so that if the sum of that formula produces a negative number, i want that negative number to just become a "0". Ive tried the IF function but could not produce any results.

I would like to see that I am continually saving on a per-day basis (as well as overtime). I allowance myself an allowance each day, but some days, I need to spend more money than that. The best solution I have to is keep a running total for myself, so that each day is affected by the preceding days. Therefore, if I spend too much, I now have a small defecit that needs to be corrected. This method keep me on track as far as saving and spending.

Question (and I copied the actual data from my spreadsheet):

Without having to manual enter the final calculations (because this is just a simple part of an overall larger, more complex spreadsheet), can I generate the values in my Value Change row, based on the information from my Running Total row?

For example, Day 1 to Day 2, I was able to incease my running total from 233 to 354 (meaning that I had saved +121 that day). Of course, this is an easy subtraction problem (Day 2 - Day 1 = Value Change). From Day 2 to Day 3, I spent way too much. The running total fell to -1198, meaning that I spent 1552 too much (that day's value change is -1552). Again, this an easy subtraction (Day 3 - Day 2 = Value Change, just like the first example). From Day 3 to Day 4, I was able to reduce my running total -1063, meaning that I was able to save 135 that day. This is my problem. Day 4 - Day 3 does not equal the value change of + 135. To get this value, the preceding formula now has to change to ABS(Day 3) - ABS(Day 4).

This is the issue. I need a formula that can work normally when the numbers are postive or when the second value is larger (in terms of absolute value). On the other hand, it needs to recognize the special cases like Day 3 - Day 4. Is this some form of a conditional function?

Running Total 233354-1198-1063-878-658-933-807-657

Percentage Change51.93%-438.42%11.27%17.40%25.06%-41.79%13.50%18.59%

Value Change121-1552135185220-275126150
