Consider letting the user type a value in to a text field and
validating the value instead of having a drop down with 101 options.
Thats just too long and will not make it easy for users.
If you decide that validating is too much for you then do this:
In your perl code create an array of hashtables with a two entries in
each hashtable. The value and a variable to denote if the value is
selected. Use one for a selected variable and zero if the variable is
not selected. The following pseudo-code should point you in the right
direction.
# create an array of hashtables with "value" set over your range
my @arr;
for my $val (1..100) {
push { value => $val, selected => ($val eq $selected_val) }, @arr;
}
$template->param( range_0_100 => @arr );
in HTML code add all the values using the loop directive.
<select>
<!-- TMPL_LOOP NAME="range_0_100" -->
<option name="<!-- TMPL_VAR NAME=value -->"
<!-- TMPL_IF NAME="selected" -->selected<!-- /TMPL_IF -->
>
<!-- /TMPL_LOOP -->
</select>
