What should I change to make my Camera CFrame loop until spawned?

I have a Main Menu Gui that once spawned cycles through 3 different camera parts. Yet it only cycles through once and I cannot figure out the correct way of coding the loop.

Also note I want this loop to break once spawned. I think im supposed to use the, "for I, v in pairs" loop but I don't know the correct way of going about this.

Thanks
