I have entered schedules, but when I go back in to edit the entire schedule is wiped out, yet it shows on the table in the Schedules on Admin Panel.  I edit the schedule and reenter all of the flight data then hit the Edit Schedule button and get the following error message back: 
There was an error editing the schedule: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1 
Here are the screenshots.  I had already entered the flight information and added the schedule, then went back into edit it and had nothing on the input screen.  When I reentered the info I then had the error pop up. 
Any ideas what file(s) is screwed up?  This started after I filed my first PIREP and I went in and updated ticket prices on the original entered schedules.  Prior to that I had 26 schedules entered and everything was working fine.
