I need help showing a select tag if another select tag's option is selected. Please see attached code. I'm also using Coldfusion so please disregard the cfif or cf tags.

Basically if the Lead_sourceID (select tag) option is 14 show the other div IntSource.

I hope this makes sense. Also, if there is a jquery way to do this I'm all ears... well in this case eyes :)
<head>

<script type="text/javascript">
window.onload=function() { 
  var sel = document.getElementById("Lead_sourceID"); 
  sel.onchange=function() { 
     document.getElementById("IntSource").style.display=(this.value=="14")?"":"none"; 
  } 
  sel.onchange(); // set the visibility onload too in case of reload 
} 
</script>

</head>

<table>

          <td> 
          <!--- SOURCE SELECTS --->
            <select name="Lead_sourceID" tabindex="19" class="required">

Wow sorry none of these solutions work. The select tag contained by the div (IntSource) should be hidden when the page loads is not being hidden. Nor is it being toggled in anyway. Not sure where the disconnect is happening as both sets of code make sense. I have included the code I have thus far, notice I commented both solutions (which are both active and I comment out one or the other when testing).

Any thoughts?
