The output on GPIO 27 is connected to a dc motor. The code is to get the motor to start from a GUI using, tkinter button widget. When I run the program RC5 the motor works fine. When I run the GUI to start the motor it says the GPIO is not set to output.

After adding the GPIO section to the GUI it no longer produces the error that GPIO isn't set up. Now it won't recognize the pulse from the raspberry pi. I've tried defining it in the GUI but it puts out the same error.

The error code is what follows:

'''
