I sense from you some slight irritation with me and my quest, and I admit I also felt was somewhat frustrated with your attitude toward my quest, though sometimes what is said in print can be misinterpretted whereas saying it verbally is much more clear. Does that make sense?
Anyway, I actually DO appreciate the fact you were unwilling to write the code for me. I DID NOT want or expect this of anyone. How else would I learn? So, thank you! However, examples and pointers which you did provide were acceptable. It was through an examination of my script that I hoped someone would point out where I was failing in coding. You finally did that and karma will shine on you greatly for it.
I removed the "br" tags (living in an HTML coding world caused me to incorporate that by mistake), and deleted the "\r". The script NOW does as I intended. THANK YOU for that. btw: not that it is worth it now, here is the exact verbiage of the error you pointedly noted was requested twice:

ERROR
This error is very likely due to a mistake in your program.

Follow the steps below to troubleshoot your error.

The "steps below" is a comment to contact our Prof (which we can't do since it is a major project he won't assist on at any level) and a link to our Science department, which provides substantially less information than is available in Ovid's CGI Course. I plan to go over that course in depth. So, as you can see, and which I should have explained (though you might not have listened until you saw for yourself) the "error" response is worthless. Sorry I was not more expressive sooner. I have trouble putting all the detail into print sometimes.
Botton line, I really am grateful for your assistance. All the best to you.
