Error Message On Form

Hi all,

I'm creating a simplified timecard entry form, and everything works perfect except one thing. When I start a new record and go to the subform and choose the day (monday - friday) it says "This property is read-only and cannot be set" but then it goes ahead and accepts the entry.

A little background, I am making the times as simplified entry (100 for 1pm, 800 for 8am, 500 for 5pm) no colons will be entered. Our hours of operation are roughly 7am until 630pm, with the occassional clock in before 6am and clock out up until 8pm or so. I have this error checking in place, it works ok, I add 1200 to the time if it is pm. Now if they are making a straight time adjustment, they enter it in as well.... for instance 8 for 8hrs holiday pay or paid time off. All this stuff works, that's not the problem.

I am thinking, maybe it might have something to do with having 4 or 5 fields set as the combined primary key on the table that holds the time/adjustment data. The reason I did the combined primary key is so they could enter in the same name, the same start date, even the same day, but the adjustment/time value has to be unique when it is compared with the start date, name, day, adjustment/time value. This table is the subform.

The weird thing is, that after the error, it lets the value stand and does not show the error again, as long as you are on this recordset. If I go back into that record and start a new entry below the others, I get the error again. While the error has no detrimental effects on the db, it is annoying.... and it still shows if I run the form off a macro with setwarnings to false.

I am including the database for review for those of you brave enough to try to understand my logic I'm sure it's something simple. I don't see anything in the properties for the form to turn off error messages like you can in data access pages, or maybe I just overlooked it. I have left one recordset in to show the functionality, it all works according to plan. This is just a rudementary database, I will fine tune it after I get past this hurdle.

Edit: I have Calendar control 11.0 for the start date, but this isn't the problem as it still did it when I had the actual field showing. That, and if you see the disparity between hours and minutes and paid time, it's because if they worked so many hours, 1/2 hour is automatically subtracted. Which is why there is a lunch adjustment field.... if they didn't take a lunch or if they took too long of a lunch.
