Issue with Google Cardboard and character movement?

So I began experimenting with the Google Cardboard recently. I encountered a problem, one I hadn’t earlier. I wanted to add some simple touchscreen input, just so that you could tap and it would move, just to test it out, but it didn’t work.

I tried using Input.GetMouseDown which did work earlier, but won’t work now.

Any help would be greatly appreciated.
