Drag And Drop Problems with basic Drag and Drop collisions

I recently got into game maker. i have already made a functional pong game but now when ever i try to make new collisions it dose not work and the objects go through each other. Its a simple procedure just when Object A hits Object B end game. The masks are correct and i all my objects are solids, Ive checked it a dozen times for errors . Anyone know whats wrongGame maker.PNG


You shouldn't need to use the solid checkbox in any of the objects. Best to leave that off, as you are handling the collision yourself with a collision event.
