Q554 How can I determine if a checkbox on a form exists?
Try:
<form name="myform">
<input type="checkbox" name="myfield">
</form>
<script language="JavaScript"><!--
if (document.myform.myfield)
alert('myfield exists');
else
alert('myfield does not exist');
if (document.myform.myotherfield)
alert('myotherfield exists');
else
alert('myotherfield does not exist');
//--></script>
