I will have to take the blaim for this one, I didn't realise that cyberpunk didn't know how to camscript at all.
Anyway, the error arises from the fact that you have no camera, like crow pointed out. Follow his instructions and you are home free =)
Oh, there doesn't have to be a space between CamSetRelPos and [5,5,1.7], I never put it in and my camscripts are flawless =)
Sorry for misleading you cyberpunk, I'll be more specific next time.
