Javascript: Variable scope question

Mon May 17 11:37:46 PDT 2004

I tried your suggestion, and get the same error with netscape 7. opera still
works fine.

Here is the actual javascript that is causing the problem. It is a bit wordy
but I don't want to edit it too much for fear of leaving out some subtle
clue.

<form name="form1" action="none">  <----I have defined form1 here!!!!

<p><input type=Checkbox name="0"  value = "USE: Lung: All specimens." onClick = "ProcessChoice(this.form,name)" > USE: Breast: All specimens.</p>
<p id="intro"><input type=Checkbox name="1"  value = "Surgical Pathology Cancer Case Summary onClick = "ProcessChoice(this.form,name)" > <a name = "1" href = "#1" title="Center this section">Surgical Pathology Cancer Case Summary </a></p>
<p><input type=Checkbox name="2"  value = "LUNG  $1" onClick = "ProcessChoice(this.form,name)" > <a name = "2" href = "#2" title="Center this section">LUNG  </a></p>

======Lots of stuff snipped out===========

p><input type=Checkbox name="119"  value = "     COMMENT ? $1" onClick = "ProcessChoice(this.form,name)" > <a name = "119" href = "#119" title="Center this section">100 ___  COMMENT ? </a></p>            

</form>     <----Close form here

<script>
document.form1[1].checked = true  <----This gives the error (form1 not defined.)

document.form1[2].checked = true         
</script>
NOTE: The javascript is actually sourced in with an src statement, with all
the proper incantations, like so:
<script src="Tail.js" language = "javascript" type="text/javascript"> </script> 
Any suggestion accepted gratefully.
