CALCULATE/COUNTROWS and date filter issue

BhaveshPatel Thanks for the reply!

Data looks something like this:

Table 1. Student_export (Student Info)

Student ID     Reg. Date   Exp. Date    Active

1                   1/1/2016    1/1/2017     TRUE

2                   1/1/2016    6/30/2016   TRUE

3                   5/1/2016    1/1/2017     FALSE

Table 2. communicationresponse_export (Response info)

Student ID     Text   Send Date     Package ID    Package Date

1                   Yes    1/5/2016       1                  1/5/2016

1                   5       2/10/2015     7                   2/9/2016

3                   Stop  5/1/2016       0                   5/1/2016

In the raw data, the 0 for Package ID was a null value (stops aren't counted as "responses" to actual questions), which I replaced as 0, with the Package IDs transformed from whole numbers into text values.

So I  count rows with a filter set on active = FALSE and Package ID = "0".

Stop Outs = CALCULATE(COUNTROWS('student_export'),'student_export'[active]=FALSE,'communicationresponse_export'[Package ID]="0")

Does that help?
