Hi Ron, its:

=IF(AND(C4-D40,COUNT(C4:D4)=2),IF(ROUND(7/(C4-D4),5)0.5,ROUND(7/(C4-D4),5),""),"")

quite a handfull I'm afraid. the actual cell reference for where the formula
result is to display is E43

the currnet formula is:

=SUM(C23-Sheet1!C23)

the first cell is on 'Sheet 2' and the second on 'Sheet 1'

Any ideas please??

Ted.

hi, no - they contain formula, sorry.

Ah -- that makes a big difference. What is the formula?

Is there a way of gettign it to ignore
the formula and return a zero when there are no numbers in the cell - it
displays the answer to a previous formula.

Post the formulas from A1 & B1.

What was the problem with the formula I suggested?

One method of outputting a zero unless A1 and B1 BOTH contain numbers is:

=IF(COUNT(A1:B1)=2,A1-B1,0)
