thanks again for the support 
so far i got the loops to count using state change detection method on the examples from the Aurduino IDE.
however, when "stepspressure" reaches the limit, it immediately counts the first step of the| stepsposition" condition.
i think that i'm not setting the limits or the trigger right. any help will be highly appreciated
