Change Scene HTML5 issue

ZombieFactory Games

Hey there,

I just can't understand why I add a Change Scene function, it just don't works on HTML5.

Any solution?

Edit: Here's the link of the demo https://svnprod.com/mfbfc/beta/

At least one of the character must be activated to make the red button green and then allow the change of the scene. But the blue one on the right don't have any conditions.

None of twice works on Firefox, The blue one works on Chrome but only once.

I don't understand...
