tab name

[puiuluipui]

Hy, i have this formula
=IF(B5<>"",IF(ISNA(VLOOKUP($B5,PLANNING!$B$4:$G$593,6,FALSE)),"??",VLOOKUP($B5,PLANNING!$B$4:$G$593,6,FALSE)),"")

"PLANNING" = an tab name.
I need something like this ( "A1" instead of "PLANNING"
=IF(B5<>"",IF(ISNA(VLOOKUP($B5,A1!$B$4:$G$593,6,FALSE)),"??",VLOOKUP($B5,A1!$B$4:$G$593,6,FALSE)),"")

"A1" = cell
And in "A1" to write an tab name. (planning ; monday ; tuesday...etc)
"A1" content to replace "PLANNING" from formula.


Thanks in advance!

Hy, i have a small problem. some tab names are "05.01.2009 ; 06.01.2009...etc"
The formula doesn't work with dates. Can you help me?

Maybe you need to format them, so instead of A1 try TEXT(A1,"mm.dd.yy")

It's working now, but one last question.
If i have in B5 "adrian" and in the "planning" tab or another tab, i
have"adrian" too, can the formula show "OK"? I don't wont the formula to show
the next cell, only to say to me that "adrian it's in "planning". Or "NO" if
the formula can't find that name.

Thanks allot!
