Bringing function out of class into main loop - zukochew - Jul-30-2018
Hello all,
Does anybody know how to bring function out of a class into main loop?
For my code, I was not able to call the function lol1 into the external main loop(dispense) for dispensing solution. It feels like there's something wrong with my logic.
Any help will kindly be appreciated!

with your code there is no GUI
you must indent
