The "param('no_unit')" parts (inside the backquotes) are evaluated as shell script. Set them to variables and have the variables inside the "`".

Update: Please note the dangers of "injecting" stuff like shell commands into your backquotes-eval if you use data that comes from the CGI! Use taint and/or the system() call with multiple parameters. (I.e. do system("perl", $param1, $param2);)
