DAX to understand period between start and end date

[C2speville]

Hi, 
I need your professional help. 

I have built up a savings table for my team which looks like attached. 

I have been trying to build up a Dashboard on PowerBi (attached). 

What I want is to have a DAX which enables to calculate the savings of a period, by taking into consideration the start and end date on my table. 

On all models I have done, it always consider the full period savings, and not the period within.

For example, If i select a period on Power BI from Jan 2024 to Jun 2024, it should show a total of 720,000 (line 1) + 330,000 (line 2)
The problem is that it doesn't understand these periods between start and end. 

I know it is possible to do it (because someone already did it for me 2 years ago), but I just can't find a way to do it myself. 

Your help will be much appreciated 🙂 

Thanks

Thanks for the reply from Greg_Deckler , please allow me to provide another insight: 
Hi  @C2speville ,

I created some data:

Here are the steps you can follow：

1. Create measure.

Measure =
var _mindate=MINX(ALLSELECTED('Table 2'),'Table 2'[Date])
var _maxdate=MAXX(ALLSELECTED('Table 2'),'Table 2'[Date])
return
SUMX(
    FILTER('Table',
    'Table'[Date]>=_mindate&&'Table'[Date]<=_maxdate),[Amount])

2. Result:

If dax gets results that don't match your expected results, can you share sample data and sample output in table format? Or a sample pbix after removing sensitive data. We can better understand the problem and help you.

@C2speville Sorry, having trouble following, can you post sample data as text and expected output?
