How can I check for the existance of a mollusc param and if so then untaint it, if it doesn't exist then no problem. Without the re match the following gives no errors at any time my $mollusc = ( param( 'mollusc' )) || ''; compared with : ( my $mollusc ) = ( param( 'mollusc' ) =~ /^(\w+)$/i ); which does. The script actually works under both circumstances and with both lines of code. Cheers Francesco -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
