This is the result of values you entered for one of more of the following assumptions:

1. If you set the Periodicity in your sales model (on the menu, select assumptions/revenues/sales models) to One Time Only. Note: Make sure you are examining the same market in the sales model that you were examining when you were looking at the customer analysis (both of the screens are market specific; see “options” at the upper right corner of the screen).
2. If you set the Retention Rate in your sales model (on the menu, select assumptions/revenues/sales models) to 0%, or to a very low number. Note: Make sure you are examining the same market in the sales model that you were examining when you were looking at the customer analysis (both of the screens are market specific; see “options” at the upper right corner of the screen).
3. You have not seeded your company with any paid-for customers (as evidenced by all zeroes on line N1). See the answer to the related question “Why do I have no new (paid) customers in a specific market?”
