    And this

     

    Measure 2 =
SUMX (
    ALL ( PPECheckInOut[ScanKitBag ], PPECheckInOut[ Crabs] ),
    CALCULATE ( VALUES ( PPECheckInOut[ Crabs] ) )

Sample data would be immensely helpful in this case. A couple things, perhaps try to Trim your data on import as well as make sure everything has the same case. To exclude blanks, wrap your aggregation in a CALCULATE clause and filter out the blanks.

HI Smoupre

 

thanks fory your reply. The Data in column looks like this.

 

ScanKitbagTag

Bag 1

Bag 2

Bag 3

Bag 4

Bag 5

Bag 6

Bag 7

Bag 8

Bag 9

Bag 10

Bag 11

Bag 12

Bag 13

Bag 14

Bag 15

Bag 16

Bag 15

 

As you can see Bag 15 is here twice. as the data is collated it will always contain duplication. i wish only to count the amount of uniquie values. in this instance it should be 16.

    OK, I used this Enter Data query:

     

    let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WckpMVzBUitWBsIzgLGM4ywTOMoWzzOAsczjLAs6yhLMMDRBMhC2GCGsMEfYYIiwyRNhkaIYiGgsA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [ScanKitbagTag = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"ScanKitbagTag", type text}})
in
    #"Changed Type"

    And this measure:

     

    Measure 12 = DISTINCTCOUNT(ScanKitBagTag[ScanKitbagTag])

    And got 16.

        You can do 2 things. Either create a new blank query and use Advanced Editor to paste in my code. Or, click on Enter Data in the ribbon and copy and paste the data you posted including the column header.
