Pete,
You are mixing accessing Cnt sometimes as a single array value and
sometimes as a whole array. I doubt that is what you want to do.
When you set a variable = value, it will either initialize a whole
array to that value or just one individual value. It depends on how
it is later referenced -- as an array such as variable[n] or just as a
variable. Once a variable[n] = value, you have cast it as an array.
Hint: sum 50, then add the next bar and subtract the one 51 back.
Best regards,
Dennis
