Did you see Dave P's reply?

If not, here are his suggestions.

=IF(A1="","SPARE","IN-USE")
or
=IF(trim(A1)="","SPARE","IN-USE")

Hello Gord,

Here is the formula I'm trying to use:

=IF(ISBLANK(A1),"SPARE","IN-USE")

A1 is blank but contains the following formula:
=IF(ISBLANK(VLOOKUP(X686,MTN_Xng_IPBH_ER01_Ports. xls!ER01_Xng_Path,4,FALSE)),VLOOKUP(X686,MTN_Xng_I PBH_ER01_Ports.xls!ER01_Xng_Path,5,FALSE),VLOOKUP( X686,MTN_Xng_IPBH_ER01_Ports.xls!ER01_Xng_Path,4,F ALSE) )

Thanks,
Jaret

The cell is not blank if it contains a formula returning "" so ISBLANK will
prove FALSE

There is no such thing as a NULL value if cell is not truly empty.

Suggestions..........? What do you want want to do with the cell?

Hello,

The ISBLANK function does not work for me when the cell it's refencing is
"blank" due to a function result. Does anyone have any suggestions?

Thanks,
