How to count rows of filtered table based on slicer selection

[char23]

I have the following table below. The months are ordered according to the [Date Rank] column with 1 being the most current month. I have a 1 measure that selects the previous month. So if March is selected, the measure is 3. If Apr is selected, the measure is 2. How can I make a measure to count the number of items/rows in the previous month and place in a card visual. So if Apr is selected as the current month, I want to count the number of rows where Date Rank = 2. And the answer would be 5 since there are 5 rows for march. I also have the following code below, but it looks like my current CALCULATE(COUNTROWS statement does not work because every time I select a month with a filter, the car visual just shows blank. It works when I pass the function a number, but not with the variable. Thank you for any help on solving this. 

ID	Status	Date Rank	Month
A	Not Late	3	Jan
B	Not Late	3	Jan
C	Finished	3	Jan
D	Not Late	3	Jan
A	Not Late	2	March
B	Re-opened	2	March
C	Late	2	March
D	Late	2	March
E	Late	2	March
A	Late	1	Apr
B	Late	1	Apr
C	Late	1	Apr

Slicer I have to select month:

First measure I have to select the date rank of the previous month:

Daterankofpreviousmonth =

VAR currentselecteddaterank = SELECTEDVALUE('Table'[Date Rank])

RETURN

IF(

    ISBLANK(currentselecteddaterank),

    BLANK(),

    currentselecteddaterank + 1

)

My current measure to count the number of rows where Table[Date Rank] = daterankofpreviousmonth. But this does not work. The card visual just shows blank. 

Countprevious =

VAR currentselecteddaterank = [Daterankofpreviousmonth]

RETURN

IF(

    ISBLANK(currentselecteddaterank),

    BLANK(),

    CALCULATE(

        COUNTROWS('Table'),

        'Table'[Date Rank] = currentselecteddaterank

 )

)

Hi @char23 ,

You can modify your MEASURE.

Countprevious = 
VAR previousdaterank = [Daterankofpreviousmonth]
RETURN
IF(
    ISBLANK(previousdaterank),
    BLANK(),
    CALCULATE(
        COUNTROWS('Table'),
        ALL('Table'), // Ensure the filter context is removed
        'Table'[Date Rank] = previousdaterank
    )
)

If your Current Period does not refer to this, please clarify in a follow-up reply.

This works when looking to count a single value. But when I add it to a visual that has grouping from another column, it shows the same number for each group.
