This is my question. I thought I was logged in, turns out I was not. Anyway, I can do this like so:

my @dates=$q->param("date");
my @loop_date=();
while (@dates) {
        my %row_data;
        $row_data{DATE}   = shift @dates;
        push(@loop_data, \%row_data);
    }
    $template->param(THIS_LOOP => \@loop_data);
}

And then in my reqinfo.html file:

<TMPL_IF THIS_LOOP>
    <TMPL_LOOP THIS_LOOP>
        <b><TMPL_VAR NAME=DATE></b>
    </TMPL_LOOP>
<TMPL_ELSE>
    <b>You Did Not Select Any Days!</b>
</TMPL_IF>

I can do it that way, but I'd like to know if I can just associate $q (my CGI object) and loop through the values of the date param somehow. That is something I am still curious about.
