I am not sure my title describes my questions fully so I will elaborate:
Let's say I have a "Make Oval Layer" node. I want to hook a "Make Random Value" node to the 'Position' input on the "Make Oval Layer" node. When I hook the cable up, it asks where I want to map (I'm not positive that's the correct term) the input value to: X>(X,0) or X>(X,X) or Y>(0,Y). Let's say I select X>(X,0). How can I connect another "Make Random Value" node to the Y>(0,Y) position?
