    If I am understanding your replies in that other thread correctly, you can use:

    gamelength += 1

    To increase the gamelength value by 1.

    This is basically saying gamelength = gamelength + 1

    as far as I can tell, there are two problems:

    1. You didn't declare gamelength either as a local variable of run(), or as an object field of GCTask.
    2. You're not re-assigning the result of the addition to gamelength. This can be done in 4 ways:

    // method 1: pre-increment
    ++gamelength;
    // method 2: post-increment
    gamelength++;
    // method 3: assignment add
    gamelength += 1;
    // method 4: regular add and assignment.
    gamelength = gamelength + 1;
