Select row in one portal and show related rows in another portal on the same layout.
I have a table of student names and a table of student grades on particular assignments. The student table and the assignment table are related through a join table. The join table is the table of student grades. I want to be able to select a student's name in one portal on a layout and have all that student's grades appear in another portal on the same layout. I've successfully been able to select particular portal rows, but I've not been able to get that students scores to show in the second portal. Can someone direct me to a tutorial or provide some guidance on how to do this?
