Dax - Previous Quarter

Hi,

Requirement :

                      1. Want to show Present Quarter and Previous Quarter in Same Visual.

Used Formula : 

                   Previous Quarter = CALCULATE   (
                                                                            COUNT('Date Master (2)'[DayOfMonth]),

                                                                             PREVIOUSQUARTER('Date Master (2)'[Date].[Date])

                                                                         )

This Measure working fine for me.



 Problem is :

                     1. When i have apply filter am not getting the Previous Quarter value.

                     2. Instead of Previous am getting Next Quarter value. Logically that is correct i can understand .



But My question is How can i get my previous Quarter value. I know have to do something on DAX. but i am cluless please help me.
