You'll need to use JS...
Eg:
--- HTML example ---
<HTML>
<BODY>
<FORM name="frm">
<SELECT name="mySel">
<OPTION value="25">Blah 1</OPTION>
<OPTION value="5">Blah 2</OPTION>
<OPTION value="83">Blah 3</OPTION>
<OPTION value="2">Blah 4</OPTION>
</SELECT>
<INPUT type="button" value="Update"
onclick="void(someUpdateFunc());">
</FORM>
</BODY>
<SCRIPT type="text/javascript">
function someUpdateFunc () {
var selValue = document.frm.mySel.options[document.frm.mySel.selectedIndex].value;
alert ("You selected: "+selValue);
}
</SCRIPT>
</HTML>
--- End of HTML example ---
This will show you what you need (I hope)...
