First:

syntax error at /var/www/cgi-bin/ds/deactivate.pl line 136, near "else"

Find your syntax error. Everything else means Jack Diddly Squat unless the syntax is good. You're missing a semicolon on a here-script further up (line 90) and you've put an extra ; on the here-script further up from there (line 84)...)

Also, is it a terribly good idea to tie() outside of the if-block and only untie within it?
