hi everyone.
im having trouble of how this would work, what im trying to do is to make sure the user pick one of the options in the form, if not it would pop up and error
<select name="choices">
<option selected value=""> please choose
<option name="SA" value="san antonio"> San Antonio
<option name="AU" value="austin"> Austin </select>
<br />
<input type="submit" name="submit" value="submit">
thx in advance
