Error in SQL Function

Hi Very New to writing functions in SQL Server

I have
alter FUNCTION [dbo].[UtilityExpense](@ClientApplicationID INT, @RecordType varchar(1))
      RETURNS money
AS
BEGIN
    DECLARE @ge MONEY
    DECLARE @we MONEY
    DECLARE @ee MONEY
    DECLARE @TotalUtilities MONEY

    SELECT
      @ge = BudgetGasExpense,
        @we = BudgetWaterExpense,
        @ee = BudgetElectricExpense
    FROM dbo.ClientInformation
    WHERE ClientApplicationID = @ClientApplicationID AND RecordType = @RecordType
   
   
    @TotalUtilities = @ge+@we+@ee  -- error here
   
      RETURN(@TotalUtilities)
END


I get an error  'Incorrect syntax near '@TotalUtilities'

I think it's because the sql statement  needs to be  delimeited. But cant figure out why. I wil be expanding on these calcualtions so I need to get vaues from the table and then performs a series of calculations returning one value

Thanks
chuck

OR you can modify it like this

alter FUNCTION [dbo].[UtilityExpense](@ClientApplicationID INT, @RecordType varchar(1))
      RETURNS money
AS
BEGIN
    DECLARE @ge MONEY
    DECLARE @we MONEY
    DECLARE @ee MONEY
    DECLARE @TotalUtilities MONEY

    SELECT @TotalUtilities =
       ISNULL(BudgetGasExpense,0) +
        ISNULL(BudgetWaterExpense,0)+
         ISNULL(BudgetElectricExpense,0)
    FROM dbo.ClientInformation
    WHERE ClientApplicationID = @ClientApplicationID AND RecordType = @RecordType
