I don't write a lot of CGI programs, so I'm not going to be an authority on use of the param() function -- but it may be complicating that line more than necessary. I'm guessing that you call it on these two fields at least twice - once (here) to see if its empty, and again later to use it.

You may want to take that out of the question by assigning each to a scalar value. Then this works:

my $tele = ''; my $mobile = ''; # uncomment to pass # $tele = 'hello'; if( length($tele) || length($mobile) ){ print 'At least one is OK'; } else { print 'both are empty'; }
