Column Name Length problem?

Good Morning Everyone,
I had a perfectly good working application written in VB that tied to a PG database on a Red Hat system with the latest ODBC driver.
After working on the app for awhile, I had to re-write the database layout based on user requests. I made some field names longer and others shorter, and generally "neatened things up". Why does "neatening things up" always break it? :).
Of course, I didn't document the old layout, so I can't compare where things went wrong. (Mental note, save printouts of the database layout)
On Friday, "select * from schedule" in the recordset.open statement would cause a "division by zero" error. In debugging it, I got up to "select id,quote_number,price_required,bid_date,bid_time,project_name from schedule" before I had to leave for the day. On Monday morning I'm going to start debugging the app from that point, but I was wondering if anyone could see anything that I would need to watch out for in the layout below. Or that would cause select * to bomb out.
thanks in advance
