If then statements

hello

i need to make an if then statment on what I would think would be a calculated field for an annual goal. 

If the Originating branch has a value then I want the annual goal to have a number value.

Here is what I have and it is not working,

=SWITCH(Fields!OriginatingBranchDescription.Value="Castor Branch","10,411,40", Fields!OriginatingBranchDescription.Value="JFK", "2,832,330", Fields!OriginatingBranchDescription.Value="Northbrook", "9,864,669")
