How Can I Increment a Counter on a Master Page?

I am working on a very complex form and have hit the proverbial wall. I have uploaded the file to the URL below and am seeking assistance in finalizing the form.

Here is the URL for the file.   https://workspaces.acrobat.com/?d=66B5k8981-WUNHJB1epZXg

There are three challenges that remain.  When I click on the "Click to Add Service Location" button on the bottom of page 2:

1. I need to add an instance of "Service_Location_Page" on the following page.  Currently, it is adding it prior to the page I just completed.
2. I need the value of "Service_Address_Type" on page 2 to change from the default value of "Primary" to "Secondary" on the new instance of "Service_Location_Page" and all subsequent instances.
3. I need the "Service_Locaton" counter at the top of page 2 to increment by +1 for each new instance of "Service_Location_Page".

Any suggestions for refinements will be greatly appreciated.
