This question follows on from this thread
http://www.experts-exchange.com/Web/Web_Languages/ASP/Q_21096299.html where I have frames and need to compare a textbox on the top frame to the bottom frame on submit

in my function below - on submit I often get an error "parent.header.WizardHeader.DealerTotal.value is Null or not an Object"?? It seems to happen if teh text box on the top of my frame is null or zero but sometimes also happens with it is populated?

how do I trap the error or do some validation if null or emptystring or..

function submitClicked(){
if (parent.header.WizardHeader.DealerTotal.value == window.document.WizardDetail.OverallTotal.value) {
          window.document.WizardDetail.submit();
     }
     else{
          alert('The Totals do not match.  Please amend.');
     }
     }

</script>

Please help!

This means that the field does not exist. Keep in mind, parent.header.WizardHeader.DealerTotal.value will only work if you call the function from the child frame. Otherwise, you have to change the path to the function call.

What If I know the field is there on the top Frame as follows?

Response.Write "<td><input type=textbox name='DealerTotal' size=1 onchange=ValidateInteger() maxlength=4 value=" & strTotalDealer & "></td>"

On the main frame I have a button as follows:
Response.Write("<br><input name='btnSubmit' type='button' name='Next >>' value='Next >>' onclick='submitClicked()'>") which calls

function submitClicked(){
      if (top.header.WizardHeader.DealerTotal.value == window.document.WizardDetail.OverallTotal.value) {
            window.document.WizardDetail.submit();
      }
      else{
            alert('Numbers dont match.  Please amend.');
      }
      }
</script>

Please explain further what you mean by change the path to the function call?

forget this.  I was calling the page from within it self so it was reloading itself and then somehow lost the reference to the txtbox.

I changed some code and it works again.

Thanks

So, as I said, the object does not exist or you weren't referencing it correctly.

And C's are the lowest form of appreciation. You are only doing yourself a favour by maintaining your open questions as the EE guidelines stipulate. Anyway, it is not a big issue, but I always find it revealing when people post questions worth very few points, don't follow up, and then offer a poor grade.
