I got it! I got it! Whew.
Ok first, many MANY huge thanks to those who've contributed to the plethora of information on this forum. I simply would not have been able to figure this out otherwise. Now I didn't just now start looking for answers, I've been searching and searching almost non-stop since this happened 24 hours ago, but with SO much info here, it almost hinders the search effort because of the amount of pages to scan before finding what you need. But it IS THERE & perseverance paid off, thank goodness!
It was a freakin SPACE that caused my woes. Extra space in php code. Somethin INVISIBLE, and yet I had to find it. Were it not for the post by Dr. Byte on "blank pages", and then the tutorial on using the debugging tool.... I'd be sitting here bald-headed, screaming, and in a puddle of tears. Instead, I'm back in business! I love this place!!
