Simulation in Excel using YASAI

I have a problem using YASAI to simulate a problem.

A hardware company sells a lot of low-cost, high-volume products. For one such product, it is equally likely that annual unit sales will be low or high. If sales are low (60,000), the company can sell the product for $10 per unit. If sales are high (100,000), a competitor will enter and the company will be able to sell the product for only $8 per unit. The variable cost per unit has a 25% chance of being $6, a 50% chance of being $7.50, and a 25% of being $9. Annual fixed costs are $30,000.

1. Use simulation to estimate the company's expected annual profit

So, my main problem is that I am supposed to use YASAI, but I can manage this easily in @risk. Can anyone help me by explaining how to set up the formulas in excel?
Or is it possible using excel functions?

Attached is the set-up I got so far and the @RISK model.

Maybe this will help?

Preetty straightforward with just vanilla Excel:

	A	B	C	D	E	F	G	H
1	Fixed
2	30,000
3
4	Sales	Price	Cost	$ 6.00	$ 7.50	$ 9.00
5	60,000	$ 10.00		$210,000	$120,000	$30,000		D5: =$A5 * ($B5 - D$4) - $A$2
6	100,000	$ 8.00		$170,000	$20,000	($130,000)
7
8		Prob	Prob	25%	50%	25%
9		50%		12.5%	25.0%	12.5%		D9: =$B9 * D$8
10		50%		12.5%	25.0%	12.5%
11
12			Expectation	$70,000				D12: =SUMPRODUCT(D5:F6, D9:F10)
