VBA problem

Hi,
I have a worksheet as below:
        columnA  columnB  columnC  columnD  columnE
        48.00        44.00      44.00       48.00

in the VBE, i will create a macro that will insert a formula into columnE.
this is my formula:
cells(1,5).formula="=IF(AND(MOD(AVERAGE(A1:D1),1)<0.1,AVERAGE(A1:D1)>1),TRUNC(AVERAGE(A1:D1)),ROUNDUP(AVERAGE(A1:D1),0)))"
(the value in cells(1,5) should be 46.00)

then i write a coding to change the value in cells(1,5)  :
if cells(1,5) mod 4 <1 then
     cells(1,5).formula="=IF(AND(MOD(AVERAGE(A1:D1),1)<0.1,AVERAGE(A1:D1)>1),TRUNC(AVERAGE
                                   (A1:D1)),ROUNDUP(AVERAGE(A1:D1),0)))"
elseif cells(1,5) mod 4 <2 then
     cells(1,5).formula="=IF(AND(MOD(AVERAGE(A1:D1),1)<0.1,AVERAGE(A1:D1)>1),TRUNC(AVERAGE
                                   (A1:D1)),ROUNDUP(AVERAGE(A1:D1),0)))-1"
elseif cells(1,5) mod 4<3 then
     cells(1,5).formula="=IF(AND(MOD(AVERAGE(A1:D1),1)<0.1,AVERAGE(A1:D1)>1),TRUNC(AVERAGE
                                   (A1:D1)),ROUNDUP(AVERAGE(A1:D1),0)))+2"
else
     cells(1,5).formula="=IF(AND(MOD(AVERAGE(A1:D1),1)<0.1,AVERAGE(A1:D1)>1),TRUNC(AVERAGE
                                   (A1:D1)),ROUNDUP(AVERAGE(A1:D1),0)))+1"
end if


The coding above meaning it will round the number.
For example, if the value is 5, it will be rounded to 4
                    if the value is 7, it will be rounded to 8
                    if the value is 6, it will be rounded to 8
                    if the value is 3, it will be rounded to 4
                                                                       
so, after i run the macro, the final value for cells(1,5) should be 48.00. Agree?
Now the value in cells(1.5) is 48.00, it will add 2 to the 46.00.

The problem is when i change the value in cells(1,1) to 100.00, the value in cells(1,5) is 61.00. By right the value should be 60.00. What can i do to the coding so that i will get the value of 60.00 in cells(1,5) when i change the value in cells(1,1) to 100. (Meaning i don't wan to run the macro again, i just have to run the macro once, and in the future, when i change the value in cells(1,1), it will gives me the correct value for the cells(1,5) ).

Anyone know how to do it?


cheers,
brandon

maybe you can concatenate all the formulas together.
like:
"if(mod(" & cells(1,5).value & ",4)<1," & _
"IF(AND(MOD(AVERAGE(A1:D1),1)<0.1,AVERAGE(A1:D1)>1),TRUNC(AVERAGE
                  (A1:D1)),ROUNDUP(AVERAGE(A1:D1),0)))" &_
",if(mod("& cells(1,5).value & ",4)<2," &
"IF(AND(MOD(AVERAGE(A1:D1),1)<0.1,AVERAGE(A1:D1)>1),TRUNC(AVERAGE
                  (A1:D1)),ROUNDUP(AVERAGE(A1:D1),0)))-1"

and so on.
you can include the old cells value in your formula "the hard way", and thus, it should work.
ok, you formula gets a little bit longer, but whatever..

Hey !   brandonsinger,

the problem is that macors dont monitor sheets for changes. so when you change the value of A1 to 100 sheet E1 will contain the previous foumula which calculates it to 61. running the macro again will change the foumula which will change it to 60.

to automate this process so that you dont have to run the macro again copy this code the workbook_change function of your work book. this code recalculates the formula whenever a value in any of the 4 columns of first row is changed

(in your workbook hit ALT+F11 and paste the following code and return to excel)

------------
Private Sub Workbook_SheetChange(ByVal Sh As Object, ByVal Target As Range)
If Target.Column < 5 And Target.Row = 1 Then
Cells(1, 5).Formula = "=IF(AND(MOD(AVERAGE(A1:D1),1)<0.1,AVERAGE(A1:D1)>1)," & _
"TRUNC(AVERAGE(A1:D1)),ROUNDUP(AVERAGE(A1:D1),0))"
If Cells(1, 5) Mod 4 < 1 Then
Cells(1, 5).Formula = "=IF(AND(MOD(AVERAGE(A1:D1),1)<0.1,AVERAGE(A1:D1)>1)," & _
"TRUNC(AVERAGE(A1:D1)),ROUNDUP(AVERAGE(A1:D1),0))"
ElseIf Cells(1, 5) Mod 4 < 2 Then
Cells(1, 5).Formula = "=IF(AND(MOD(AVERAGE(A1:D1),1)<0.1,AVERAGE(A1:D1)>1)," & _
"TRUNC(AVERAGE(A1:D1)),ROUNDUP(AVERAGE(A1:D1),0))-1"
ElseIf Cells(1, 5) Mod 4 < 3 Then
Cells(1, 5).Activate
ActiveCell.Formula = "=IF(AND(MOD(AVERAGE(A1:D1),1)<0.1,AVERAGE(A1:D1)>1)," & _
"TRUNC(AVERAGE(A1:D1)),ROUNDUP(AVERAGE(A1:D1),0))+2"
Else
Cells(1, 5).Formula = "=IF(AND(MOD(AVERAGE(A1:D1),1)<0.1,AVERAGE(A1:D1)>1)," & _
"TRUNC(AVERAGE(A1:D1)),ROUNDUP(AVERAGE(A1:D1),0))+1"
End If
End If
End Sub

R_Rajesh,
What is the meaning og the "target.column" ?
Where the parameter that pass to this function come from?

cheers,

target.column gives you the column number of the cell thats being changed. say you changed the value in B4, here the column is 4 so target.column will contain 4 and B is second column so target.column will contain 2. As soon as you change any value a workbook_change event will be triggered, we can trap these events using worksheet of workbook funcitons and the parameters from these functions will contain various information regarding the current state of the application.

in vbe press F1 go to answer wizard and make a search for type application object events.

btw did it solve the problem

in my previous post the above line should read

here the row is 4 so target.row will contain 4 and B is second column so target.column will contain 2

what is wrong with concatenating the formulas and inserting the old value of cells(1,5)?
this'll do also and is simple
