The first code says Forbidden chars again. So show the input and output, quit making us guess (and when I say 'output' I mean the new string, not the number you're trying to calculate). As far as which approach, don't worry about it. Just pick one (as long as it works).	[reply]

Think about it. How does that help (read again what output I asked for)? When you're trying to determine input and output to something...just print the something... `my $molform = <STDIN>; print "Molform before: [$molform]\n"; s/\s+$//, s/H(?![a-z])\d*//g for $molform; print "Molform after: [$molform]\n";` [download] Although hazylife may have nailed the problem...you need to learn how to provide useful debugging information.
