Excel/looking up information if


Hi Tom

I have two worksheets.  Worksheet A contains data worksheet B is blank.  I would like cell A1 in worksheet A to be populated with information from cell A1 in worksheet B be as long as cell A1 in worksheet A is empty.  If it is not empty I would like the next cell in worksheet A (ie cell A2) to be populated.

Is this possible?

Christopher Mitchell,

If you wanted to use intentional circular references, you might be able to craft something like that.  Each cell would have to be populated by a formula.  As you describe it, both A1 and A2 would contain the same value.  If the value in A1 of sheet2 will be updated and you want to accumulate values, that would be more complex, but possible using circular references.

Your countryman, Stephen Bullen has example files that illustrate this.
go to
and look in the worksheet function section (second section) and I believe the first two or three example files are related to this type of thing.
