What happens if you add a variable in between. Instead do either: {{{ sub display_page { my $a_server = shift; my $a_pass = shift; . . . } }}} (shift is short for << shift(@_) >> ) Or: {{{ sub display_page { my ($a_server, $a_pass) = @_; } }}} > Hope that helps > Regards, Shlomi Fish > Robert Gorrebeeck > Sr. EDI Apps Dev Analyst > Coventry Workers' Comp Services > Solutions to Restore Health and Productivity > Office: (972) 725-1484 > gorrebeec...@cvty.com > www.coventrywcs.com > -- ----------------------------------------------------------------- Shlomi Fish http://www.shlomifish.org/ List of Portability Libraries - http://shlom.in/port-libs Deletionists delete Wikipedia articles that they consider lame.
