Hidden fields being visible if containing data

[#1]

Hello,



I have a shipping form that allows the user to specify local or internationl shipping thru radio buttons. The int. fields are hidden when the form is first opened. If international is selected the address fields change to allow international addresses. How can I save that state of the form so that when it is reopened the international address is visible?



Suggestion: Add some java to the intialize section of the form that checks if there is data in the hidden fields and then turns them on?



Is this the right approach?

Figured it out:



if (AddressIntEField.rawValue !=null) {

AddressIntEField.presence = "visible", relevant="+print";

}

else {

AddressIntEField.presence = "invisible", relevant="+print";
