If I go to a meeting and pay $12.00 a week, is that $12.00 for every week that I go? Do I have to pay if I miss a week? Say if I went today and paid the $12.00 and then didn't go for two weeks, do I have to pay for three weeks then when I return, or just the $12.00 again? I hope that makes sense.

You must pay for the weeks you missed as well as those you attended.
