I am having some problems dealing with a colon delimited list inside a cgi script. My lists will not show up correctly inside a hidden() input within the browser. Here is a snippet: 
    defined $param{selected} 
        ? ( $param{selected} .= ":$file" )
        : ( $param{selected} = $file );

    join ( "", map {
        hidden (
            -name    => $_,
            -default => $param{$_},
        )
      } keys %param )

Within the script, hidden() seems to forget everything after and including the first :. If I change the hidden() to Dumper, the correct stuff is displayed in the browser window, showing that $file is properly defined. Running the script from the comamnd line also returns the bad results so it isn't specifically a browser problem. What is strange is that if I run: 
perl -le 'use CGI qw/ :standard /; print hidden( -name => "foo", -defa
+ult => "foo:bar" )'

hidden() seems to do the right thing.

Is there something I am missing in this snippet? Is there a better way to pass a list within cgi arguments?

Thanks in advance.
