Passing variable as an input file to AWK comand

Hi,

I would like to compare 2 files using awk, which I can do by using:
Code:
awk 'NR==FNR{a[$1];next} (NR > 32 && $2 in a) {print $0}' File1 and File2.

If the name of the File1 is in another file (for example, column 4 in File 3) then how can I pass this column 4 to the awk command.

Thanks in advance.

Kind regards,
Ezhil
