Sandy,
If you are asking about a rate for extended stays in your rate table, you determine when a customer's request qualifies as an extended stay, which would have a different nightly charge than your basic one. In the box, you put in how many days would be necessary to qualify and then you put your discounted rate for longer stays. For example, if you put a 7 in the box, then stays of 7 days or longer would be considered "extended" and charged at whatever rate you assigned to longer stays. You are the one who decides whether you even want to have that rate. I do not, primarily because I only board one or two dogs at a time,
From your rate table, the information you entered means that you don't discount for extended stays., Which is fine, but you didn't need to fill out anything to achieve the same result. Leaving it blank means you don't offer it.
Is that what you were asking about?
