Alternately, if you want a formula to fill all the terms for a given order, the value in the Maximum Term Number should be. N = 1/2 y^2 + 3/2 y. For example, if you wanted all the orders for 7 up to X0Y7, N = 1/2* (7^2) + 3/2* (7) = 49/2 + 21/2 = 35. So you would type 35 for the Maximum Term number.
