balance from previous quarter

[BeginnerBI]

Please I truly need your help.  I am trying to get the value from the previous quarter.

I only have one table, and my only date is quarters. I attached a picture to see if I can explain myself.

I will give you kudos all the compliments but please help me on this. Greatly appreciated. Example

Please try

Prev. Quarter =
CALCULATE (
SUM ( 'Table'[Column] ),
'Table'[Date] = EOMONTH ( MAX ( 'Table'[Date] ), -3 ),
ALL ( 'Table'[Date] )
)

Thank you so much!
