ISBLANK() validates only truly blank cells and not the ones having formulas....

=IF(H9="","","yes")

Hi Again everyone.

Ok another problem I am now having.

I have the following formula in column H

=IF(ISNA(VLOOKUP(TRIM(A135),'Current running April
2010'!$1:$65536,1,FALSE)),"",VLOOKUP(TRIM(A135),'C urrent running April
2010'!$1:$65536,1,FALSE))

In Column I simply want to say

=IF(ISBLANK(h9),"","yes")

But it's returning yes even if the cell is blank.

Any ideas?

Thanks
