Display Previous Quarter Only

[EVEAdmin]

Hello all!

I created the following measure to calculate the current quarter sales

3QuarterToDate = TOTALQTD([QTYTotal],'Calendar'[Date],Sales[SubCategory]="Digital Manuals")

I also created the following measure to calculate the previous quarter sales

3PreviousQuarter = CALCULATE([QTYTotal],PREVIOUSQUARTER('Calendar'[Date]),Sales[SubCategory]="Digital Manuals")

 They both work fine. I can insert them to a table and they display the corresponding data.

I would like to create a visual card, with the previous quarter total only. 
When the current quarter is 1, the card must display QTR 4 previous year
When the current quarter is 2, the card must display QTR 1 same year
When the current quater is 3, the card must display QTR 2 same year
When the current quarter is 4, the card must display QTR 3 same year

How I can achieve that, please?

Please see this video for how to create a relative YearQtr index column on your Date/Calendar table (centered on Today()).  Once that is in place, you can put your measure in the card and set the visual filter for when that new columns "is" -1.

@mahoneypat That works, thanks a lot.
If I set the filter to "is -1", then I get QTR3 last year.
If I set the filter to "is 0", then I get QTR4 last year, which is what I am aiming at.
