Unity isn't compiling standard api calls?

Hi everyone.

Feel a bit embarrassed asking about this, but I just can't wrap my head around it. Here's my code:

 void Update()
 {
     int nTouches = Input.touchCount;
     
     for (int i=0; i<nTouches; i++)
     {
         Touch t = Input.touches[i];
     }
 }

And here are my errors:

 Assets/GenericLib/Input/TouchInput.cs(77,46): error CS0117: `Input' does not contain a definition for `touchCount'
 Assets/GenericLib/Input/TouchInput.cs(83,49): error CS0117: `Input' does not contain a definition for `touches'

Extremely confused. Any help appreciated greatly. :)
