circular reference formula

Hi

I have a formula with circular reference. When a I put any valur in any of
these reference cells the formaula gets overwritten by the value. Is there
any way that I can put values in any of these cells without overwriting the
formuls to try various permutations. Below is the example:-

Cell A B C
500 10 2%
Formula +C1*A1 B1/A1

Cell B1 & C1 are having formula with cicular reference. What I am trying to
get is that if I change the B1 value to 50 from 10, then C1 should
automatically change to 10% & vice versa. OR If C1 is changed to 10% B1
should change to 50 so that I can try as many combinationas possible.

The problem here is that once i put "50" in B1 or "10%" in C1 the formula
gets overwritten with the absolute value.

Would be thank ful if anybody can suggest any solution for this?

Abhi

I have done a similar thing with Sin/Tan/Cos formulas and Pythagoras
calculations.

I use 2 rows, with answers in the second row (A2, B2, C2) being dependant on
what cells are filled in the first row.

The formulas are all in the second row and can be protected to ensure that
they are not overtyped.
I also format the cells A2, B2, C2 in bold red to indicate that they are
calculated.
Try entering formulas as follows and then enter data in either A1, B1, C1.
In your case you will need to format C1 and C2 as Percentage with 0 decimal
places.

A2=IF(AND(B1<>"",C1<>""),B1/C1,"")
B2=IF(AND(A1<>"",C1<>""),C1*A1,"")
C2=IF(AND(A1<>"",B1<>""),B1/A1,"")

If you really want to have only a single row of cells, then you could use a
macro triggered by the worksheet_change event to update the values in the
other 2 cells.

Regarding the macro, if the value in A1 is changed (to say 1000) which of B1
or C1 would you rather changed?

If you want B1 to take precedence then this VBA code should do it:
Private Sub Worksheet_Change(ByVal Target As Range)
Application.EnableEvents = False
On Error GoTo ee
Select Case Target.Address
Case "$A$1", "$C$1"
[b1].Value = [c1].Value * [a1].Value
Case "$B$1"
[c1].Value = [b1].Value / [a1].Value
End Select
ee:
Application.EnableEvents = True

End Sub
Alternatively if C1 is to take precedence then:
Private Sub Worksheet_Change(ByVal Target As Range)
Application.EnableEvents = False
On Error GoTo ee
Select Case Target.Address
Case "$C$1"
[b1].Value = [c1].Value * [a1].Value
Case "$A$1", "$B$1"
[c1].Value = [b1].Value / [a1].Value
End Select
ee:
Application.EnableEvents = True

End Sub

Enjoy

You will need some VBA macro code (Worksheet_Change). Do you mind?
