Thanks Majenko,
Couldn't get back on for hours for some reason.
So I take it
lcd.write(4); and
lcd.print(4);
are the same?
I use the lcd.print all the time (without the BYTE keyword) and it works fine.
Anyway, I tried it as lcd.print(4); and it compiled, just have to change everything to a 16,2 display from a 20,4 that was in the original code and fire it up.
