expanding a variable inside of a CGI param call	Can't Post

I'm trying to design a subroutine that will allow me to pass variables to the $q->param() routine within the CGI module.

here's my code so far.

Code

sub Handle_Media { 
   my $name = shift; 
   @Files = $q->param("$name_files");  
   @Delete = $q->param("$name_DEL");    
   more code here ...

If for example I passed "LIBRARY" to the subroutine, I want it to load into @Files all the values of the param "LIBRARY_files". I've checked that the values are being passed, so I know that's not the problem. How do I get it so @Files will be the values of the param named "$name_files"???

Thanks

Change your @Files and @Delete lines to this:

@Files = $q->param("${name}_files");
@Delete = $q->param("${name}_DEL");

or ...

@Files = $q->param($name . "_files");
@Delete = $q->param($name . "_DEL");

Those both should work. The second (although a few characters longer) should be more readable/understandable.
