fender telecaster thinline

How to properly set up a Vox Wah Wah??? ?
Please dont just give me. “Push all the way forward and hear click and play.” I am doing that and it IS working. Just not properly. I click it and instead of being able to use the wah effect, it acts as a horrible distortion pedal. It just goes dead. I dont get the sound i want. PLEASE HELPPPPPPPPPP. By the way i have a Marshall MG50 DFX, a fender thinline telecaster, and a marshall distortion pedal, and the wah wah if thats any of the reasons.
it won’t work with the distortion pedal.
