SQL 2005 IF not working fine - if-statement

Question

I've created an if statement to control if a customer discount is right. I take the sales volume of its previous year, control if it is in the exact range, then if it is not I need to write the right discount to apply. My problem is that this suggested discount is not the right one. I'll show you the code.
Before I give a sample customer data.
Discount Applied is 60 %
Sales Volume 2016--->€ 13.895.90
Sales Volume 2015 ---> € 25.686.92
This is my query:
DECLARE all variables that i need......
SET #Anno1 = YEAR(GETDATE());
SET #Anno2 = YEAR(DATEADD(year,-1,GETDATE()));
SET #Anno3 = YEAR(DATEADD(year,-2,GETDATE()));
SET #datada = DATEADD(DAY, -15, GETDATE());
SET #dataa = GETDATE();
----- set discount sales volume ---
SET #40 = '€ '+ REPLACE(CONVERT(varchar, CAST('1500.0000' AS money), 105),',','.');
SET #50 = '€ '+ REPLACE(CONVERT(varchar, CAST('15000.0000' AS money), 105),',','.');
SET #60 = '€ '+ REPLACE(CONVERT(varchar, CAST('150000.0000' AS money), 105),',','.');
SET #70 = '€ '+ REPLACE(CONVERT(varchar, CAST('200000.0000' AS money), 105),',','.');
SET #80 = '€ '+ REPLACE(CONVERT(varchar, CAST('500000.0000' AS money), 105),',','.');

The result of this query for #ScontoPrevisto, suggested discount is wrong, it is between 70% and 80 % but as you see the previous year sales volume is about 25000 so the right discount must be 50-60%.
I dont' understand why. Instead for some customer, reslt is good.
Another customer has
Sales Volume 2016--->0
Sales Volume 2015 ---> 0
Discount 60%
Result is greater then 80 % instead to be smaller than 40 %.
I wait for your answer. Thank you guys!
