Try this:

=IF(COUNTIF('Past RDW'!$L$3:$L$780,$L11)=0,"",
IF(VLOOKUP($L11,'Past RDW'!$L$3:$AI$780,16,0)="","",
VLOOKUP($L11,'Past RDW'!$L$3:$AI$780,16,0)))

This is my formula

'=IF(ISBLANK(VLOOKUP($L11,'Past RDW
'!$L$3:$AI$780,16,FALSE)),"",(VLOOKUP($L11,'Past RDW
'!$L$3:$AI$780,16,FALSE)))

I am getting #NA when there is not a match so need to have a combo of
isblank and iserror... is this possible?

thanks in advance! jane
