App Designer Switch Component

Hi,

I am still working on the app that I was writing before. We added vibration motors to the circuit and want them to vibrate at a certain force level and if they are selected to be used. I cannot get them to vibrate with the forces. I have attached the code if anyone has an idea to help me get this to work. I thought I had it, but I may not understand switch components enough.

Thanks in advance!
