Thanks for jogging my memory. I seem to be so focus on this for a couple of hours and didn't happen to see that I make one minor typo with adding the six $_SESSION data. I assign the odbc_result() to it, so forgot to increment the number on one of them, so the rest after it was off by one. So, it's my fault.
One question though, wouldn't it make more sense to have the result be either as 0 or 1 (or true or false) instead of blank or 1. I first interpret the blank as something is wrong with the script or functions. Thanks, Scott F.
