Hopefully someone can assist me with this -
I have a form that has a drop down list, I want this list to query a specific SharePoint list data connection based on the value of another drop down list within the form. For example - the 4 SharePoint lists are North, South, East and West. If user selects West Region the product list will query the West product list for selections. I can successfully query a single data source but for the life of me I cannot discover the proper rule or filter to make this action work.
This form once in production will be used with Form Services.
