dynamic select box

[Anon]

Hi,

How can I build a dynamic select box, so that the user selected value will retained after error handling and returning to the form page if any fields are left blank.
Any help appreciated 😉.

<select name="agegroup">
<option value="">
<option value=1>15-19</option>
<option value=2>20-25</option>
<option value=3>25-35</option>
</select>

like so:

<option <?
if($agegroup == "15-19")
echo "selected";
?> value=1>15-19</option>

for each option.
