UI Text Component being reset on player when built

http://pastebin.com/n2Sn5QRe

heres where I think the problem is, this script is attached to a First Person Player controller, everything works just fine in the editor, but when i go to build it, the UI shows the placeholder text that I have in the editor, but not my pickup countText or my WinText, and I also cannot pick up the pickups! All of these are controlled by the script above, I think what is happening every time I build is that the PlayerController script is breaking where none of it works.

plz help
