LastNonBlank formula help

[pokdbz]

I need to get the total for the Count of Last Status = "Completed" per store

Result

Store 2 = 3

Store 3 = 1

Here is how the data is setup

Store                Role                   Status

2                       Bakery               In Progress

2                       Bakery               Completed

2                       Seafood            Completed

2                       Deli                   Completed

2                       Meat                 In Progress

3                       Bakery               Completed

3                       Deli                    In Progress

This gets me the last status.  But I'm not sure how to get it to count only the Completed.

xmeasure =

        LASTNONBLANK

        (

            'StoreTasks'[Status],

            'StoreTasks'[Status] IN { "Completed" }

        )
