Hi

In cell A1 I have a vlookup formula and =if(sheet1A1="","",sheet1a1) which
returns the correct result when blank.

In M1, I have the formula =if(a1="","",networkdays(k1,k3))-1 This also
returns the required info when sheet1A1 has something in the cell, but when
sheet1A1 is empty, M1 returns #VALUE!

I have tried in M1 =if(iserror(networkdays(k1,k3))-1 etc, but get the same
result (#VALUE!)

any help appriciated to tidy up the spreadsheet by removing #VALUE!

regards

Brian
