Conditional Enabling/Disabling Textbox using dropdown and visa/versa

I've reached an impasse and need some help to make it over this hump. I'm working on an asp page that will have conditional validating of a textbox and a dropdown list. I created a function that looks like this:

<script LANGUAGE="javascript">
    function Toggle_AcctNumber(){
      
      if(document.Getparms.DropLineItem.value != [NOI])
        document.GetParms.AcctNumber".disabled="true";
     
      else if(document.Getparms.AcctNumber.value.length != 0)
              document.GetParms.DropLineItem.disabled=true;
    }
  </script>

and here is how i call that function in the dropdown and textbox....

 <SELECT name="DropLineItem" id=DropLineItem onclick = "Toggle_AcctNumber();" size="1" style="HEIGHT: 22px; WIDTH: 320px">


<input type="text" id="AcctNumber" name="AcctNumber" onchange = "Toggle_AcctNumber();">

can anyone tell me what i'm doing wrong? Thanks....

Yes, you need to view your page source. ASP prefixes additional text to all web controls at render/run time. So view source, get the name that ASP generated and replace .DropLineItem.Disabled with the full name you found in the rendered HTML. Do this for both of your document.GetParms calls and you should be back on track.

Now all you should replace is the .DropLineItem. with .{NEWNAME}. and the same for the other control.

The control names look the same to me when I view the page source.

replace it with

<script LANGUAGE="javascript">
    function Toggle_AcctNumber(){
     
      if(document.getElementById("DropLineItem").value != "NOI")
        document.getElementById("AcctNumber").disabled="true";
     
      else if(document.getElementById("AcctNumber").value.length != 0)
              document.getElementById("DropLineItem").disabled=true;
    }
  </script>

I think rawinnlnx9 is confusing ASP with ASP.Net.

The following works for me, try comparing it with what you have:
<html>
<head>
   <script type="text/javascript">
     function Toggle_AcctNumber()
     {
        if (document.GetParms.DropLineItem.value != 'NOI')
          document.GetParms.AcctNumber.disabled = true;
        else if (document.GetParms.AcctNumber.value.length != 0)
          document.GetParms.DropLineItem.disabled = true;
     }
   </script>
</head>
<body>


    <form name="GetParms" id="GetParms">
      <select name="DropLineItem" id="DropLineItem" onclick="Toggle_AcctNumber();">
         <option value="NOI">NOI</option>
         <option value="One">One</option>
      </select>

      <input type="text" id="AcctNumber" name="AcctNumber" onchange="Toggle_AcctNumber();" />
    </form>

</body>
</html>
