A family of Microsoft relational database management systems designed for ease of use.
I did design the forms the way you instructed in the first place, but was having trouble filtering the students according to the CenterCode so I took it apart and just to show you I designed the one in the screenshot. If this is hard enough, then, do I have to revert back to the one you have instructed? Will I be able to enter the marks of each student per center for each month of the year? I'm ready to do that too if I can link the combo box to filter the form according to the CenterCode.
