[Javascript] how can I check to see if a text box has a number or a string in it???

[Peter Brunone]

Scott,

	A few questions/comments:

	What is the error?

	You don't have to say ==true; it's implied, i.e. you're asking for its
existence.

	Generally, your form will be subordinate to the document object, so you'll
need to say parent.FrameName.document.formName.fieldName.value (try putting
.document after TransDetail).

	Other than that, make sure your names and cases are correct, and if you
want to see if a form field value is numeric, don't forget to parseInt() or
parseFloat(); otherwise, everything will be a string.

Cheers,

Peter

|//  if( isNaN(parent.TransDetail.myform.ClosingYear.value)==true )
|//        {
|//            alert("You must select a Year");
|//        return false;
