using isblank and isna in one statement

Is it possible to use both isblank and isna statement. I have a vlookup in which I want to use both and can't figure out where to use the AND statement. I've tried a few ways to merge but nothing seems to work!

Any ideas?

I want both to display nothing(the cell to be blank) if there is a error and nothing in the cell. Hope this makes sense.

=IF(ISBLANK(VLOOKUP($A$4,sheet2!$F$4:$BD$2003,47,FALSE)),"",VLOOKUP($A$4,sheet2!$F$4:$BD$2003,47,FALSE)

=IF(ISNA(VLOOKUP($A$4,sheet2!$F$4:$BD$2003,47,FALSE)),"",VLOOKUP($A$4,sheet2!$F$4:$BD$2003,47,FALSE)

Thanks.

maybe try it with or()

=IF(OR(ISBLANK(VLOOKUP($A$4,Sheet2!$F$4:$BD$2003,47,FALSE)),ISNA(VLOOKUP($A$4,Sheet2!$F$4:$BD$2003,47,FALSE))),"",VLOOKUP($A$4,Sheet2!$F$4:$BD$2003,47,FALSE))

Nice to hear you've figured it out.
Thanks also.
