For a nice clear explanation of a two-way lookup see

The AND part will need to read
=IF(AND(B3<"", C3<"",

Or you could use
=IF(COUNTA(B3:C3)=2,

Hi, i have this code:

=IF(B3<"",IF(ISNA(VLOOKUP($B3,PLANNING!$B$4:$G$50 ,6,FALSE)),"??",VLOOKUP($B3,PLANNING!$B$4:$G$50,6, FALSE)),"")

And i need two criteria, and to make the code something like this:

=IF(AND(B3,C3<"",IF(ISNA(VLOOKUP($B3,PLANNING!$B$ 4:$G$50,6,FALSE))),"??",VLOOKUP($B3,C3,PLANNING!$B $4:$G$50,6,FALSE)),"")

If B3 and C3 content is find in "PLANNING!$B$4:$G$50", than the code to
give
the "6" cell content
