Switch Gun with dastardlybanana fps kit

I cant seem to switch gun correctly. I watched the tutorial and i know how to make a secondary attachment(like the masterkey shotgun) but i dont know how to actually make it switch to another gun intirely. I have tried everything i can think of and i need help

What should happen is you put more than one weapon in the ‘weapons’ array in PlayerWeapons. Then just press the number keys to switch between those weapons. Does this work in the demo scene?
