Limit Dynamic No of checkboxes 1

[struth]

I want to limit the number of checkboxes a user can check. But they are dynamic checkboxes so a page could end up with 3, 10, 20 checkboxes in it. It takes the number they can check from an asp variable <%=myCheck%>.

Any ideas

<script>
function limit(inObj){
allInput = document.getElementsByTagName(&quot;input&quot
numAllowed = 5
numFound = 0
for (x=0; x<allInput.length; x++){
if (allInput[x].type == &quot;checkbox&quot{
if (allInput[x].checked){
numFound ++
}
}
}
if (numFound > numAllowed){
alert(&quot;too many&quot
inObj.checked = false
}
}
</script>

<input type=checkbox onClick=&quot;limit(this)&quot;>
<input type=checkbox onClick=&quot;limit(this)&quot;>
<input type=checkbox onClick=&quot;limit(this)&quot;>
<input type=checkbox onClick=&quot;limit(this)&quot;>
<input type=checkbox onClick=&quot;limit(this)&quot;>
