I believe these problems have the same solution.

1st problem:
I would like to be able to remove the zero that is placed 3 digits from the
RIGHT. The values a
66014
8004
8015

The values should look like:
6614
804
815

2nd problem in the same mproject:
I would like to be able to remove the values, text, and/ or spaces that are
16 places from the RIGHT.
