Hello again

I successfully solved all my problems, well, at least I hope so
I used the "BEFORE" and "AFTER" method of 3run because of one reason:

My 3DGS is version 7.5 and does not include some of the functions that are used in some examples given (str_cut & str_trim).

I had to fiddle around a lot until everything worked out, but in the end its not just easily possible to 'replace' a part of a txt.
The only option was to edit it in a string and replace it after.

Maybe I should upgrade my 3DGS in the future to gain some additional functionality
