http://marvelvscapcom.wikia.com/wiki/Template:Toggle
I've tried to implement the switch/toggle feature into this wikia. My two choices are MvC3 and UMvC3 <-- default
I can't click MvC3 to change the picture. I've kept the switch template exactly the same as your one. Same with the toggle but it just doesn't work.
This is the page that needs help.

Many thanks.
