Need help with Sidki filter causing problem

[z12]

Thanks for the explanation.

Indeed, I wasn't sure what the intent of the $INEST subroutine was.
Mentally, my biggest problem was determining the scope of the match.
The variable nature of it confused me, and frankly, still does.
I desperately wanted to see an & or &&. It's just the way my brain works.

Armed with your explanation, I plan on doing some testing till I get it.
Thanks again.
