I want to select one of the radio buttons and then click a region of the map to do a search. so if I have 3 radio buttons, the user will select one of the radio buttons and the select a region on the map to do the search.

Here is the code:

<p align="left"><font size="2">number of people interested </font></p><p align="left"><font size="2"> <input type="radio" name="radiobutton" value="radiobutton">single</font><font size="2">
<input type="radio" name="radiobutton" value="radiobutton">couple <input type="radio" name="radiobutton" value="radiobutton">
family <img src="Mapsa.gif" width="337" height="350" border="0" usemap="#sa"><br>
</font><input type=hidden name="db" value="homes"><input type=hidden name="do" value="search_results"><input type=hidden name="dp" value="999999"><input type=hidden name="uid" value="default"></p>
