"gen:44:attempt to perform arithmetic __sub on nil and number"
gen (the API):
mTime = true function setColor(bc, tc) if not bc then bc = 32768 end if not tc then tc = 1 end term.setBackgroundColor(bc) term.setTextColor(tc) end function printLeft (y, str, bc, tc) setColor (bc, tc) term.setCursorPos (1, y) term.write (str) end function printRight (y, str, bc, tc) setColor (bc, tc) term.setCursorPos (w-#str+1, y) term.write (str) end function printCentred (y, str, bc, tc) setColor (bc, tc) term.setCursorPos (w/2-#str/2, y) term.write (str) end function printHere (x, y, str, bc, tc) setColor (bc, tc) term.setCursorPos (x, y) term.write (str) end function getTime () return textutils.formatTime (os.time (), mTime) end function drawError (str) waiting = true while waiting do setColor (2048, 2) term.clear () printCentered ((h-1)/2, str, 2048, 2) printCentered (h-4, "Press any key to continue", 2048, 2) local event = os.pullEventRaw () if event == "char" then setColor (1, 256) term.clear () sleep (1) os.reboot () end end end function printTime (x, y, bc, tc) local tTime = getTime () if x == "default" then x = (w-#tTime)+1 end printHere (x, y, tTime, bc, tc) end
HASH.lua (the main file):

Also, I believe that I was testing the gen.drawError function by putting in the wrong side for the drawPanel function.
