Thank you for your response. Where is the Fields Settings tab?
I have "Fields management" tab or menu item, which is the 3rd from the left at the top. Inside the Fields management there I see the list of the different fields. Some basic information is shown in columns for each field.
In the older version of Payment Form there was a column labelled "Order", just between the "Publish" and the "ID" columns. This is where I ordered my fields, but in the newer version of PF this "Order" column is not there. Maybe this option to change the order of the fields is somewhere else, but I just don't see it.
I'm still stuck on this. I definitely prefer the older version for this ability to order fields in a form.
Thanks for your help.
