DAX Measure Sort by issue

I have a card on a report page that displays selected choices from slicers and I am having an issue obtaining the correct sort order for one of them. The measure is based on a simple table of two columns, 'Grade' (text) and 'Order' (whole number).  

Grade   Order

Teachers1
 2
P43
P54
K5
16
27
38
49
510
611
712
813
914
1015
1116
1217

My DAX Measure statement is:

List of Grade Values: =
VAR __DISTINCT_VALUES_COUNT = DISTINCTCOUNT('Grade_Sort_Order'[Grade])
VAR __MAX_VALUES_TO_SHOW = 17
RETURN
    IF(
        __DISTINCT_VALUES_COUNT <> __MAX_VALUES_TO_SHOW,
        CONCATENATE(
            CONCATENATEX(
                TOPN(
                    __MAX_VALUES_TO_SHOW,
                    VALUES('Grade_Sort_Order'[Grade]),
                    'Grade_Sort_Order'[Grade],
                    ASC
                ),
                'Grade_Sort_Order'[Grade],
                ", ",
                'Grade_Sort_Order'[Grade],
                ASC
            ),
            ""
        ),
            "All"
        )
    As you can see, the CONCAT statement is set to order by  'Grade_Sort_Order'[Grade], whereas I need it to sort by  'Grade_Sort_Order'[Order] but the statement does not recognize the 'Order' column in the table. If I change it from Grade to Order I get the following error: 
"A single value for column 'Order' in table 'Grade_Sort_Order' cannot be determined. This can happen when a measure formula refers to a column that contains many values without specifying an aggregation such as min, max, count, or sum to get a single result."
So using the order by of Grade, the order results of a selection of P4, 1, 4, 10 is: 1, 10, 4, P4 when what I need is P4, 1, 4, 10.
I have tried changing the column format to text and using 01, 02, 03, ect. but this did not work.
I have probably over explained this but I feel it is best to be wordy rather than vague.
Any thoughts are much appreciated.

    Anonymous - Here is where you are limiting your table. I would replace what is in red bold below with this:

     

    'Grade_Sort_Order'

     

    So, just the table, which would include all columns in the table.

     

    VAR __DISTINCT_VALUES_COUNT = DISTINCTCOUNT('Grade_Sort_Order'[Grade])
    VAR __MAX_VALUES_TO_SHOW = 17
    RETURN
        IF(
            __DISTINCT_VALUES_COUNT <> __MAX_VALUES_TO_SHOW,
            CONCATENATE(
                CONCATENATEX(
                    TOPN(
                        __MAX_VALUES_TO_SHOW,
                        VALUES('Grade_Sort_Order'[Grade]),
                        'Grade_Sort_Order'[Grade],
                        ASC
                    ),
                    'Grade_Sort_Order'[Grade],
                    ", ",
                    'Grade_Sort_Order'[Grade],
                    ASC
                ),
                ""
            ),
                "All"
            )

    Anonymous - If I am understanding your code correctly, it looks like you are only feeding CONCATENATEX a single column "Grade" and thus your Order column is not available. You will need to start with both of your columns being fed into CONCANTENATEX and then you should not have a problem.

      Greg_Deckler  - Hi Greg, and thank you for the responce.

      Sorry for the delay in getting back with you. Right after I made my post I got slammed with work and couldn't get back until now. 

      I have tried manay different ways to "feed CONCATENATEX" with the (Grade_Sort_Order.[Order] column but nothing I try has worked.

      Where, in my expression above, would I reference the [Order] column?

      Thank you for your help.
