Filter Drop Down Menu

Filter Drop Down Menu

In FormA, I have 2 drop down menus.

The first drop down, DropDown1, is the Batch No.

The second drop down, DropDown2, is the Student Name.

In FormB, I put DropDown1 and DropDown 2 as lookups from FormA.

What should I do in FormB, if I select Batch No. = 20, then the DropDown2 only display the respective students from Batch 20?
