I have a cgi script where I need to discern a reply of zero vs. no reply, a text box with zero as a response and retrieved using cgi.pm, appears the same as no response (left blank), can I do this server side or will I have to use javascript?

Within the same script I use ConfigReader::Simple, looking at the code for that module it is just beyond my perlish grasp, I am trying to pass an array of items into a single key, is the most straightforward way (I almost said _only way_) to do this passing a list of items such as
key "1,2,3"
then split it? (which seems very unperlish)
