Dynamically Using SUM X for allselected values

[cdawidow]

Hi guys I have a simple measure called Average Sales = AVERAGEX(VALUES(FISCAL YEAR),TOTAL SALES))

Which is essentially calculating the average of total sales across all present years. 

The formula works as expected, but I find that my totals are being calculated as the average and not the sum of any column values I select.   So I have been using Sumx(values("any column field"))

My question is, I am using around 3 column fields as my values with this sumx calculation to get the sum of all average sales of all the selected values and I am having to create a sumx calculation for each.  Is there a way to create only 1 sumx calculation witht he ability to sum x all selected values??

[Sum of Avg Sales Over Column] =
SUMX(
    DISTINCT( Dimension[Column] ), // use VALUES if you've got RI problems
    CALCULATE(
        AVERAGE( FactTable[Sales Amount] )
    )
)

// HASONEVALUE is redundant in 
// your code since if there's only
// one T[Column] value visible
// in the current context, SUMX
// will sum up over just one value.

Thanks for the response.  Yes, I understand that values removes duplicates. 

But lets say I have 2 columns each with unique values ( Customers and Products) along with my average sales measure stated above.

Is there a way to build  a sumx calculation that follows the following rules:

If(Hasonevalue( column name),average sales, sumx(column name),average sales)

Most likely your formula like SUM( VALUES( "any column field" ) ) is incorrect. VALUES removes duplicates which means that if you have 2 records in a table that have the same value in the field, the value will only be counted once in SUM. Don't think this is what you'd want.

The rest of the post is not within my grasp.
