A family of Microsoft relational database management systems designed for ease of use.
First, Ok, the subforms are fixed and working. Now forget them for the moment. Now we have to concentrate on getting a set of records to Append to tblStudentProgress.
So, the SQL statement you posted has some issues. First, I told you NOT to join tblCourse to tblstudentProgress.. Second, what is CourseScore? If that is the score for the current period, then it is in the wrong table. It needs to be in tblStudentProgress.. I've said this all along. We had the table structure set, why did you change it?
Finally, I said the query should produce a record for each student for each course. Did you run the query? I'm sure it didn't so that should have told you something was not right.
Again, the first step is getting this query right. Make those changes and let me know if the query now works the way I said it should.
