Several problems related to programming controls

We have attempted to program motors to the shoulder buttons and the right D-pad on vex edr block code studio on a Chromebook with no result. The motors work when programmed to different buttons. We have tried different remotes and cortexes to no avail. Please help.

Also when trying to program manually with out designating a drive train, the studio produced this message. “One of your program blocks has an invalid device assigned to it. Please check that your devices are still valid.”

You have to post your code!

You may have renamed a motor… When you do that you have to go through each block that uses it and change it. It’s a known bug.
