'screen' not declared in this scope error message

Hey,

Just wired up my arduino uno + 1.8" TFT screen, got the TFTGraph sketch running (had to install the latest version of the IDE software to get the screen to work). However, I want to change the “fill” pattern to just a dot at the value point. But when I try to use “TFTscreen.point(xPos,yPos)”, I get the error message “error: ‘screen’ was not declared in this scope”. I originally got the idea to use that function from the arduino website itself. Anyone run into this before?

Extarct the TFT librray to its default folder name and put that folder in the arduino library folder and restart Arduino and try.
