> But the second example still prints out empty variables to the html page.
yeh on second thought that is not a good example here.. it may possibly work if you did
if(!($item =~ /^0$/))
though there should be a prettier way but i cant think of it right now..

yes the [^0] says that we do not want to match 0.. so if there is anything other than 0 it returns success..

comparing strings with operators does not work.. or is not always defined.. my perl is rusty at best.. i just always use matching to compare strings..

this matching that i did is using regexes (regular expressions).. essential to know if you are going to use perl.. regexes are a huge part of perl.. just search google for perl regex or regular expressions and the like you will find plenty of info..
