Thanks for jogging my memory. Found the problem, I forgot to increment the column count on the odbc_result so, left the rest of the column off by 1 count when I added 6 columns (odbc_result) to the $_SESSION. How goofy of me!
Anyway, I first thought that data returned as blank meant something is wrong with the script. But hey, wouldn't it make more sense if the output can be either "1 or 0" instead of "1 or blank", it would help to make life be made easier because we forget that a blank can also meant false....
