    Help with hiding div tags based on radio selection

    I am new to JavaScript and realize that I'm probably just missing something simple. I have two radio buttons and I want a a certain div tag to display based on which button is selected. I've cut out the extra coding and made a very basic example of what I'm trying to do. If you could be of any help I would greatly appreciate it.

    The error that I'm getting is stating that "document.form.techspecsub" is either null or not an object.


    Code:
    <script type="text/javascript">
    
    function showhide_areabldgreq() 
    {
       if (document.form.techspecsub[0].checked) 
          {
          document.getElementById("areabldg").style.display = "inline";
          }
       else 
          { 
          document.getElementById("areabldg").style.display = "none";
          } 
    
       if (document.form.techspecsub[1].checked) 
          {
          document.getElementById("reqpo").style.display = "inline";
          }
       else 
          { 
          document.getElementById("reqpo").style.display = "none";
          } 
    }
    
    </script>
    
    
    
    <form>
    <input name="techspecsub" value="Enter Area" type="radio" 
    onClick="showhide_areabldgreq()" />Enter Area<br>
    
    <input name="techspecsub" value="Enter Requisition" type="radio" 
    onClick="showhide_areabldgreq()"  />Enter Requisition
    </form>
    
    <div id="areabldg" style="display:none">I'm Area</div><br>
    <div id="reqpo" style="display:none">I'm Req PO</div>

    Add highlighted:
    Code:
       if (document.forms[0].techspecsub[0].checked) 
          {
          document.getElementById("areabldg").style.display = "inline";
          }
       else 
          { 
          document.getElementById("areabldg").style.display = "none";
          } 
    
       if (document.forms[0].techspecsub[1].checked) 
          {
          document.getElementById("reqpo").style.display = "inline";
          }
       else 
          { 
          document.getElementById("reqpo").style.display = "none";
          }
    Hope that helps.

    Set the radio buttons to have values and change one of their names...
    Code:
    <input type="radio" value="YOURVALUE" name="techspecsub"><input type="radio" value="YOURVALUE" name="techspecsubb">
    Then change Your javascript to check for the value...
    Code:
    <script type="text/javascript">
    
    function showhide_areabldgreq() 
    {
       if (document.form.techspecsub.value="YOURVALUE") 
          {
          document.getElementById("areabldg").style.display = "inline";
          }
       else 
          { 
          document.getElementById("areabldg").style.display = "none";
          } 
    
       if (document.form.techspecsubb.value="YOURVALUE") 
          {
          document.getElementById("reqpo").style.display = "inline";
          }
       else 
          { 
          document.getElementById("reqpo").style.display = "none";
          } 
    }
    
    </script>
    That Should Work
