Sum of products based on title.

[Aurelio]

Good morning all

I'm struggling with an issue in Power Bi. 

Context:

Table 1 (Flexmail) with title of the newsletter, responding language and products mentioned:

Title	Lang.	Product
Veri-te et Longvida	NL	C³urcumin/Resveratrol
Veri-te et Longvida	FR	C³urcumin/Resveratrol
Nieuwsbrief  dec 2022	NL	Liv-Protect/Liv-Dtox
Nieuwsbrief  dec 2022	FR	Liv-Protect/Liv-Dtox

Table 2 (Producten) with a detail of the newsletter, product and no.

Newsletter	Article	Nr.
Veri-te et Longvida	C³urcumin	P10001
Veri-te et Longvida	Resveratrol	P10002
Nieuwsbrief Oak Pharma dec 2022	Liv-Dtox	P10003
Nieuwsbrief Oak Pharma dec 2022	Liv-Protect	P10004

Table 3 is the value entries with no, sales amount and quanity, date. 

Goal: 

I a click on a title of a newsletter I want to get:

- The sum of the corresponding products in amount and quantity.

- Starting from the launchdate of the newsletter.

I tried several solutions with filter and related but none of them worked. It looked a lot easier than it is. 

Thank you very much in advance!
