Count Records Based off of Date Calculation

I have written a measure to determine the next upcoming Friday's date based off of today's date.  I'm sure there is a better way, but basically I used a combination of CALCULATE, IF and WEEKDAY to determine how many days needed to be added to TODAY to get the upcoming Friday, if not Friday already.

Now I am wanting to use this calculation in another measure to determine how many items are due by the upcoming Friday; however, I get the error that a calculation can not be used as  a filter.  Is there a way around this?

My data has a "Due By" date, so I want to count the number of rows that are not in a CLOSED or REJECTED status (another column in the rows) that are "due by" the upcoming Firday.

The masure I was trying is below.

Due_By_FRI = CALCULATE(COUNT([defect_id],[defect_status]<>"Closed",[defect_status]<>"Rejected",[ECT]<=[FRI_DTE]

I get the below error

A function 'CALCULATE' has been used in a True/False expression that is used as a table filter expression. This is not allowed.

If I change [FRI_DAE] to TODAY(), then it will count the number today by TODAY or if I do TODAY()+/- n it will give me the number due by today +/- the number.  However, I want it to due this automatically.

Any suggestions would be greatly appreciated.

Thanks,
