hello

i figured out both issues

1. destroy Document Variables
single by name:
ActiveDocument.Variables("FullName").Delete

All variables by loop:
For x = ActiveDocument.Variables.Count to 1 Step -1
ActiveDocument.Variables(x).Delete
Next x

2. Not returning correct Sentence Number. i entered the formula wrong, i actually assigned it, once removed it works

only outstanding issue is... Is this a solid way to achive my stated goal? thanks
