I am writing a program to enroll students and I'm having a big problem. i am using a datamodule in which I put all my tables. If I enroll students i alter my course and student table. They are linked on each other with a nr ( key in student) Student is the master table. When i couple 2 Dbnav on these tables and there is more than one course for one student I get an EInvalidGridOperation =>> Grid index out of bounds/date/invalid. I solved this by putting two table componenets on the form where this is necessary and now it works. What causes this problem???
Please help me, it's for my final report....
