"This joint will result in conflict" problem when trying to connect two joints to the same part

Hi guys , I'm new to Fusion 360 , I'm trying to make a robotic arm , I want the the two vertical long components to connect together with the horizontal one, so that the two vertical one will move together when moving the horizontal one , but when I tried to join the left vertical one with the horizontal , It shows a warning and didn't work.This is what I want : 

and this is the file :

I did not get into a lot of detail, but a lot of times, when you are trying to apply a revolute joint, and there is a conflict, replacing it with a cylindrical joint will work.  This is likely some small discrepancy in geometry/orientation that prevents the components from being positioned to satisfy the revolute.  You should investigate that, but in the meantime, a cylindrical will work.
