How to make block which works like a VHS recorder?

Hi, i want to make VHS recorder with no playback (just inserting and putting out tapes). i currently have custom model and tape with badly made procedure.

I am beginner with this stuff and usually i am doing simple mods. Currently i want to make this device. I tried to make procedure for it, enabled GUI for that block and when i want to assign the procedure to the recorder, it says "missing dependencies". I posted 2 screenshots where is my actual attempt. what i am doing wrong and how could i fix it? thanks for any advice.
