Split a value across 12 months/A year

Hi , I was able to create a date table to capture and divide the value by 12 Months.

The issue now is that it does not filter when i make selection simply because there is no connection between the Date Table and Main Table.

i took below steps:

1. I created a date Table and added a column with the below

Priority Amount = 
var _start=DATE(2024,1,1)
var _value=[Priority]
var _end=EOMONTH(_start,11)
return IF('Date'[Date]>=_start&&'Date'[Date]<_end && DAY('Date'[Date])=1,_value/12)

Where priority is a calculated DAX measure from the below table.

Priority = sum(Unit_UrgentNeed[Priority_Amount])

I was able to get the below:

If i add a slicer, and include Title column, If i select any of the title values, it does not filter the new date table.I guess a relationship needs to be created within this 2 Tables.

Thanks in Anticipation.
