I am solving a mass balance for my wastewater class and need help using excel for find my unknowns. I have solved down to this EQN; 35,000=2367(SRT)/(1+.088*SRT) + 31.2(SRT)^2/(1+.088*SRT) + 88.8(SRT)/(1+.06*SRT) + 449*SRT + 224.6*SRT
SRT is my unknown.

to allocate funds to various organisations with a number of constraints (see spreadsheet attached I work in Excel 2007 but saved the file in 2003):
1. No negative growth can be allowed (Column M which is difference between columns Q and B) and I therefore added Column N to bring the growth in Column R to 0% for those which had a growth of less than 6%.
2. Minimum growth however allowed should be 6%
3. Maximum growth allowed should be 50% (not all need to have 50% growth)
4. The balance of the allocations to organisations with growth more than 50% should be used to "equalize" allocations proportionately between the other organisations with growth lower than 50%
I am trying to solve a set of simultaneous equations by using SolverOk function in VBA.
I dont want to use the 'SetCell' option so, I wrote the following
SolverOk MaxMinVal:=1, ByChange:= Range("V34:V36")
SolverAdd CellRef:=Range("AK4:AK6"), Relation:=2, FormulaText:="0"
SolverSolve
but I get an internal memory error. However, if I use the solver dialog box directly from excel and not through a macro and keep the 'Set Target Cell' as empty, I get the right solution.
How to solve table with filter which needs to be copy to other tab.
Example: One tab has table with filter. Issue is with another tab which needs to be copy but issue is that another tab will further investigate with additional columns. Can be solved this issue as first tab will filter and change all rows order and another tab should read content with added columns.
Is it possible in excel to find the equation for a curve?
I have 6 known x,y data points on a curve. I need to find the equation for the curve.
Can excel solve an equation for x with two variables.
Example: 102=125000(X-910)/50000.
I need excel to solve for X
The variables are 102 and 125000
I need the formulas to solve for the ARC length AB.
(How) can Excel solve this?
I will have to solve many variations of the 1 inch length and/or vary other measures.
Known's
Arc radius 1.5
Slope angle 31 degrees
Slope intercept to center of Arc Diameter 1
Circle B radius .75
Circle B is tangent to Slope
Solving the Segment length AB would be a bonus.
Given a list of numbers and a list of 'allowable' operators, come up with a specific total. ("The numbers game" on countdown on BBC2.... ooooh Carol Voderman)
For example, given the numbers 1, 3, 4 and 5 with valid operators +, -, /, * come up with a solution equal to 15. All numbers must be used once only. Use operators as often as required. The specific example above was given to me and I personally think its not solvable (might be a practical joke). But I am wondering is it possible to prove this through assertions or develop an algorithm to solve such puzzles. I can get 14 and 16, but not 15....
I am attempting to create a formula that is including numeric values in multiple cells but I want to exclude cells that have an "N/A" value. I am calculating the blended average price using the volume and price from multiple cells but some cells don't have volume or price but an "N/A" instead. The blended average price should be $68 but how do I calculate that including all the cells...even the cells including the "N/A"
Attachment example included.
Need to solve the formula in the file. Is it possible to solve this in just one move? in that case.

In column A I have a date AND time entered. By the way, this is not via cell format, I have manually entered, say today's date and the current time. In column B I have a future date and time.
Basically, column A is the date and time a problem was given to me. Column B would be the date and time I resolved the problem. Now for the formula....Column C needs to spit out whether the problem was solved between 24 and 48 hours OR less than 24 hours OR greater than 48 hours.
I'm having trouble using the worksheet copy command in a VBA subroutine. I have the following line in my code:

VB:
Function f1(Matrix As Range)

let me start by saying that I know an example workbook would be useful here, but the part I'm struggling with is the [managementroster.xlsm] file, and there is A. no way I can release it to the internets and B. its so huge/complicated I couldn't even begin to reproduce a portion of it, scrubbed of data, and hope to maintain its functionality in a meaningful manner.
[Code]....
This formula checks a staff number on this spreadsheet, and then goes and looks at the staff number on the roster. Once found, it returns that staff members roster, but changes any manager codes in the MRC list to Mgr, and changes all other roster codes to Free.
I now need this formula, before altering roster codes to Mgr or Free, to only return codes that are a match for another table (or after really. I don't particularly care, so long as only codes are shown that match data from another table). I think an index/match function would do the trick, but this forumula is already at the edge of my excel ability, nesting another function within it is completey beyond me. The relevant cells for the index/match function would be:
This first Match function targets the column. $E3 is the date required, $BA$1:$DN$1 is the range the dates are entered in
Match: Lookup value = $E3
Lookup array = '[ManagementRoster.xlsm]Vacancies!'$BA$1:$DN$1
match type = 0
This second Match function targets the row. $A$4 is the department name, $B$434:$B$452 is the range where all departments are entered
Match: Lookup value = $A$4
Lookup Array = '[ManagementRoster.xlsm]Vacancies!'$B$434:$B$452
match type = 0
Index: array = $BA$434:$DN$452
So I think my final function is

But I have absolutely NO idea where it would fit within my first formula, or how to code it so that my original formula only reproduces results that are found in both sheets, or anything.
I have created a List in excel of various tasks. (See attached example.) Each row contains one cell with a function which equals the cell above it and to the right. So the function for cell C3 would be D2. The only importance is that the cell mirrored is always the cell one above and to the right. However, now I would like to be able to rearrange this List, but the “one up and to the right” function will now be all over the place.
Is someone aware of a function which will target a relative location instead of an exact cell?
I keep getting the "You've entered too many arguments for this function" error.

I have been looking around have this much code from this site, modified. What I am trying to do is calculate numbers by a position with cells D through K having numeric values. I have 'hardcoded' the cells (D2, E2, etc in the code below), but in reality I only want the current row (so if the formula is on the 2nd row, I want D2, if it is on the 3rd row, I want D3).
My problem is obviously the formula isn't working because I am not correctly tying back to the spreadsheet (Positioncalc.xls). When I put the formula in the spreadsheet it works, but in my script I get 0 everytime.
My Script:
Function Position(rCell As Range, Optional RightPosition As Boolean)
Dim vResult
Select Case rCell.Text
Case "QB"
vResult = (2*D2) + (2*E2) + (2*F2) + (4*G2) + (2*H2) + (1*I2) + (4*J2) + (3*K2)
Case Else
vResult = "Invalid Position"
End Select
If RightPosition = True Then
Position = vResult
Else
Position = "Position not valid"
End If
End Function
So, when I put =Position(A2,True) I expect to see the formula results of those cells calculated based on the position (QB, HB, etc with their unique formulas).
My next challenge after this is to highlight certain cells based on the Position. So if A2 = QB, I want cell D2 boldface and Red, etc. I have seen some scripts on colors and such here, so I might be able to figure it out.
I have a range of cells, for this example I will use 2.
Cell E17 = 77/170
Cell E18 = 8/9
Using the following formula: =SUM(RIGHT(E17,FIND("/",E17)))+SUM(RIGHT(E18,FIND("/",E18)))
This bring back an #VALUE! Error as the second part of the formula keeps picking up "/9" however the first part works fine, displaying "170"
Now if I use:
=SUM(RIGHT(E17,FIND("/",E17)))+SUM(RIGHT(E18,FIND("/",E18)-1))
It all works. The problem is that I need this to be automatic using the above way means having to add a "-1" to every formula for a cell with only 1 char to be added.
Using the formula:
=SUM(RIGHT(E17,FIND("/",E17)-1))+SUM(RIGHT(E18,FIND("/",E18)-1)).....
I have a tracking sheet (attached) that has many functions, but I'm having trouble with two of them. First of all, I have a Worksheet_Change event set that when a cell is cleared, it fills the cell with a formula to use the record above it as a default value if another cell is equivalent. This worked when I first wrote it, but now it seems to break every other time I use it. When assigning the formula it returns a Method Default/FormulaR1C1/Offset failed error message. It seems to be different for each one, each time and I can't figure out what the problem is.
The other problem I'm having is that I wrote a BeforeDoubleClick event to expand or contract any given record, or series of records. this too worked when I initially wrote it, but now is only hiding one row when it should be hiding eight or more.
I'm not terribly versed in VBA and totally baffled as to why I'm having these problems. As I side note, any ideas to clean up any of the code and make this run smoother (as ther will be many more series added when complete).
I have a user defined function in one VBA module that I'd like to call from another module, so I would normaly scope it as "Public".

Is there a way to have a function that is available to other VBA modules in the same project, but not to Excel as a worksheet function?
