if i correctly understand, you try to redefine variable inside
cgi-generated html, yes? i think it is incorrect.
check, what your browser does with this sample:
**********************
#!/usr/local/bin/perl
use strict;
use CGI qw/:all/;
print header;
print <<END;
<html>
<head><title>test</title></head>
<FORM action=$ENV{'SCRIPT_NAME'} method=get>
<input type=hidden name="param1" value="param1_val">
<input type=hidden name="param2" value="param2_val">
<input type=hidden name="param1" value="redefined1">
<br>
<INPUT name=submit type=submit value="test">
</FORM>
END
print "param1 = ",param("param1"),"<br>";
print "param2 = ",param("param2"),"<br>";
print '</body></html>';
**********************
on my ie5 i got this:
param1 = param1_valredefined1
param2 = param2_val
