Thanks! Your answer was very helpful and I found it to be 99.9% correct. However, it ended up that I needed to attach that code to my SSN field and not my Submit button. So, in my case, this is what it looks like when I click on my SSN field after I added the code:
topmostSubform.Page1.SSN::preSubmit:form - (JavaScript, client)
SSN.rawValue = "";
I did the same thing for my date of birth (DOB) field:
topmostSubform.Page1.DOB::preSubmit:form - (JavaScript, client)
DOB.rawValue = "";
I tested the form after the changes and it worked great.
You are a life saver. Thanks again!
