Hi Cecil

>I keep getting an error thqt says: "No overload for method Biz_Tier, takes 2 arguments."

This is because you are passing two arguments to Biz_Tier and the compiler cannot find a Biz_Tier method/parameter signature that accepts two parameters. So, either your call to Biz_Tier is incorrect or, you simply need to create an overload for Biz_Tier that accepts two parameters. An overload is simply a way to have calls to the same method that accept a different number and/or type of parameters.
