SOLVED: Dynamically dropdown <select> form validation

[eluser]atno[/eluser]
Hi,

I have a <select> that is created dynamically from a database and it must validate to check if any option is selected. The options are about 58 and only one can be selected. If a user selects something but forgot to enter his/her name on submit the select will be reset, he/she will type his/her name and now when submit is pressed again there will be a new error showing that no option is selected!
I read the user_guide but I don't get it how to form_validate a <select> with so many dynamically generated options. What I understand is that every set_select() but be entered manually.
Is there a way to do it and i have missed the big picture?

Here's the code

Code:

<select name="test" size="1">

          &lt;?php

             foreach ($tests->result() as $test) {

                echo "<option value=\"$test->id\">" . $test->name . '</option>'. "\n";

              }

            ?&gt;
</select>

Cheers,
