Thanks all, many great ideas which I've percolated into my final solution.
If you see any problems, please drop a post :)
I chose to instead of checking the perl variables, check the CGI parameters - which made much more sense, thanks for the ideas Monks;
my @varlist = qw(var1 var2 var3);
foreach (@varlist) {
if (!defined $cgi->param($_) || $cgi->param($_) eq "") {
&complain($_);
}
}
Where &complain() can translate var# into the HTML side field name (ie. "Phone number", instead of 'phone').
Cheers all;
JP,

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
