There is Javascript code online that goes like this:

Checkbox code:
<input name="ATCCheck[]" id="ATCCheck[]" type="checkbox" value="<?php echo $row_WADAcounsellors['counsellorID']; ?>" onclick="setChecks(this)" />

<script type="text/javascript">
//initial checkCount of zero
var checkCount=0

//maximum number of allowed checked boxes
var maxChecks=3

function setChecks(obj){
//increment/decrement checkCount
//if they checked a 4th box, uncheck the box, then decrement checkcount and pop alert
if (checkCount>maxChecks){
alert('you may only choose up to '+maxChecks+' options')
