Before everyone else says "Use CGI.pm", your html_table sub has a logic bug - you are not closing the table (the statement just before the return). You have

$tableP.="<TABLE>\n";

when you should have

$tableP.="</TABLE>\n";
[download]

Depending on your browser, this can really stuff up the appearance of the HTML.

Update:As well, you are not generating compliant HTML code. For example, you are missing the normal HEAD and BODY tags. While some browsers can handle these omissions, and generally interpolate them, this is not a good idea. It you really want to continue with your own "hand generated" code, you may want to have a "start_html" and "end_html" subroutines that do all the other html bumph.
