Depending upon the option selected in a combo box, how to perform the corresponding a

can be done using javascript

example:

<script language=javascript> //<!--


function ChangeINT(obj){
 var strInput = obj.value
   alert('you chose '+strInput);

  
}
// -->
</script>

<input type=radio name="sample1" ID="sample1_on" value="option1" checked onclick="ChangeINT(this);">option1<br>
<input type=radio name="sample1" ID="sample1_off" value="option2" onclick="ChangeINT(this);">option2

or use javascript to submit the form and vbscript to use the value of the checkbox submited if the messages are pulled from a db.
