Need help if you can

[LittleLadynRed]

I to not want to add a date but I also do not want it to add anything until I put in an number in c25 or e25 or f25
Please help. Don't know if I am explaining it correctly.


=IF(ISNUMBER(B26:F26),"",G25+B26-E26-F26)
or
=IF(ISBLANK(B25:F26)," ",G24+C25-E25-F25)

Not really sure what you want here, but both ISNUMBER and ISBLANK both expect a single cell ref, not a range

If you need to test for a cell containing info before the formula fires...'
=IF(B26="","",G25+B26-E26-F26)
