Hi Jeremy!
Thank you so much for you quick response! The problem with making the acc Var global is that I need it to reset to 0 in each trial (or what I call sets). Because I need the experiment to end only when the participant makes three mistakes in a set, not overall. If, for example, the participant makes one mistake in setA, other in setC, and another one in setD I need the experiment to continue. Only when the participant makes three mistakes in the same set then the experiment should end.
Thank you so much in advance!
M.
