Can someone tell me what is wrong with this code? I've got everything except the 24,36,48, and 60 month calculations working. They turn out to zero everytime. I think it has something to do with where I input noMonths, but I can't make this work. Can someone help please????? Pretty please???? Oh and they will say 24,36,48,60 at the ends of the 0.00 because I was trying to see if it would read noMonths.

Thanks
