perl & html

I never quite know what forum to go to...so forgive me in advance.

I have a form where users input text into text boxes. When they click submit the text is sent to a databsae and a cgi page is called and the user's input is displayed in a drop down box. This is my code:-

print '<select name=Choice>';

while (my $ref = $sth->fetchrow_arrayref)
{
for (my $i = 0; $i < $numFields; $i++)
{

if ($i)
{
printf ("%s</option>",$$ref[$i]);
}
else
{

printf ("<option value=%s>",$i);
}
}
print '<br>';
}

print '</select><br><br>';

My problem is:
If the user input from the html page already exists in the database i want to bring up the selection list on the CGI script with that term pre-selected???????
Does anyone have any idea how this can be done?
Extremely grateful...

All you have to do it output "selected" into the option box and that option will be the one "selected".

Code:
<select name='poo'>
<option value='foo'>Foo
<option value='bar'>Bar
<option value='blee'>Blee
<option value='bloo' selected>Bloo
</select>


So figure out how to do that with your code, using some kind of conditional.

Honestly, creating forms without using CGI.pm is painful. Here's a VERY easy way to do this with CGI.pm:
Code:
my $ref=$sth->fetchrow_arrayref();
my $form;
$form.=$q->start_form();
$form.=$q->hidden(-name=>'control',-value=>'updatestuff');
$form.=$q->popup_menu(-name=>'poo',-values=>$ref,-default=>'bloo');
$form.=$q->submit();
$form.=$q->end_form();
print $form;


What a time saver! Of course, you can print the elements as you go too.
