I don't understand this -- you are trying to Mix MV tags with the
perl in the key parameter, and to no effect. While you could do 
"[calc] ... [/calc]", there is no point in trying to do things this way.

                  key=`
                          $tmp = $Scratch->{product_category};
                          $tmp =~ s/[ ,].*//;
                          $tmp
                  `

is correct.
