Good day!
I simply cannot believe the mistake that I made but, while testing, I neglected to revert some variables prior to my last update, which is what caused the initial error you reported above. As for your other comments, I will need more time to review everything---as I don't wish to repeat the issue just described, which was brought on by too much haste on my part.
Thank you again for continuing to make me aware of these problems!
