Urgent need help with Formula and or Code Problem

Hi

I have attached my spreadsheet, if someone could help me I would appreciate this greatly.

In the spreadsheet I have the number of presentations I do, how many sales I make etc.

The main thing I would like to know is, is this the right way of setting it up? Is there a better and easier way?

Also, I am not sure if the percentages are correct, you see if someone comes in and they sign up, then that is a "S", I also have "NS=NO SALE" which are people who don't sign up on the day and I have "FF=Finance Fallover" which is not my problem, because they wouldn't have been able to go ahead anyway. I want to have a true percentage of clients that purchase, that purchase and then "FO+Fall Over" and ones that fall over due to finance.

Any help would be greatly appreciated.
