awk gsub with variables?

Hey,

I would like to replace a string by a new one. Teh problem is that both strings should be variables to be flexible, because I am having a lot of files (with the same structure, but in different folders)
Code:
for i in daysim_*
do
    cd $i/5/
    folder=`pwd |awk '{print $1}'`
    awk '{ if (NR==14) {gsub($2, $folder); print} }' ill_5_06.hea
    cd ../..
done

But of course it doesn't work. So the problem is how to deal with the variable $folder in gsub?

Thanks for any suggestions, Sam.

Description
       Use the command to display the full pathname of the specified folder.  If you do not specify a folder, displays the pathname of the current

       of the specified range as possible.
