Quick question about the CALCULATE function

[PoorBIGuy]

I have a customer sales table like this:

I am trying to calculate total sales by customer for year 1 and year 2, and wish to have an IF formula to determine "large" or "small" based on year 1's total sales by each customer.

I used a CALCULATE(SUM(),ALLEXCEPT(Customer)) formula to get the customer total sales. But when i do the IF function to determine large or small, it fails.

For example, i try to say if year 1 sales is over 80, it's a large customer. it fails for customer D...

Just wondering if anybody has any insights?

@PoorBIGuy So this?

Measure = 
  VAR __Sales = CALCULATE(SUM(),ALLEXCEPT(Customer))
  VAR __Result = IF( __Sales > 80, "Large", "Small" )
RETURN
  __Result
