Don't feel foolish, we all had to learn by trying.

I admire you perserverance.

I agree with CheshireCat
The problem you seem to be experiencing is due to you trying to "force" that approach into an example where it simply does not fit. It must make sense to do it before you can or should do it.
For your problem are better alternatives.

Just use them and learn of those options.

Glad I could help. Thanks for the reply.
