variables not carried over from this script - batch-file

Question

this script takes a video file as input and after preliminary renaming extrapolates values such as title and year or episode along with a search strings strict for finding duplicate videos and loose for finding all episodes of a series. it then does a controlled filebot rename for the file.

none of the variables are carried over to the script that called for them. I can't for the life of me figure out why except it must have something to do with endlocal or disabledelayedexpansion, which look fine to me as far as I can tell.
