Operations smile problems

We are trying to plan events in school for operation smile. Usually we do an open mike event, but there is just too much going on in school so there is a big problem to get approval from the teachers. We were also thinking of a fun day on the weekend and a dance but right now the prom tickets are being sold, so there is a problem finding a good time. It is quite frustrating that it is so hard to do a good event for raising money to operation smile. I think we just have to keep trying and not give up!
