Stepper motor+keypad+LCD screen setup? Need help ASAP...

The goal of my project is to input the code for a combination lock onto a keypad, and have the stepper motor move accordingly.   I currently have two codes. One code just handles the motor, which works fine. The second code handles all three devices. The Keypad and LCD work as expected in the second code, but when we get to the motor it gets stuck. I have tried all the troubleshooting I know how to do, and have come up with no viable results as to where the problem lies.

You can access the Google Drive folder with both of these codes here.


If you need anymore information please feel free to ask! The code needs to be done as soon as I can manage,  so all help is appreciated smiley

Define what the problem is, exactly ? There's a lot of code there, there are a lot of things that can be made much simpler.
