Thank you! Thank you! It would have taken me forever to find my mistake. Jason, you are the biggest asset WA has going for its products.
Everything now inserts into the db like clockwork.
However, now the add course page has the "Dreaded Headers Already Sent" problem.
Warning: Cannot modify header information - headers already sent by (output started at /addcourse.php:287) on line 481
I tried troubleshooting per your advice here: http://www.webassist.com/forums/posts.php?id=19285
I looked for blank spaces and lines, reinserted the code in the area, took out any comments that looked extraneous, but the page either stops at the Room Name line (287) or on the header("Location: ".$WA_redirectURL); line (259) for the course room location insert. As my track record for spotting the obvious appears to be a little shaky, would you please take (what I hope) is one last look at this thing...
Is the error there caused by the datepicker error code? Line 88 & 344. CourseDateAdd is listed in both places. Is that a problem? Does the code starting on line 88 even need to be there anymore? (My head hurts...)
