I have created an interactive form with show/hide certain subforms with add Instances, with calculations using Designer 8.1.1. I have saved the form as a dynamic xml form (I can see that this form is compatible with 7.0.5 or higher) Now when the form is online I have customers who use 8.0 or 7.0.5 They can open the form but not everything shows or they cannot add a line. IN other words the form gets useless.
Is there a way to sort this problem out? Can I add script which looks at the adobe reader the user uses and then give a popup that he needs to upgrade? Maybe put the link in the popup? Do I use form ready to execute the popup?
How are your Customers getting the form? Are they calling a program that calls Form Server to render the form? It is possible that when calling form server you are not specifying that the form needs to be rendered as dynamic.
