Merging same Item from portal 1 with total amount in portal 2

Post

After many hours working on that problem, i'm here  in coummunity. Also i tried tip form LaRetta, but i could find the solution (I didn't understand the way, sorry).

You see my layout, which is based on recipe table (in german named "rezept").

In portal 1, I put in the preposition steps with all the ingredients. You can see, that Pos. 1 and 2 have the same article, it's "Olivenöl". One time with mass 5, one time with mass 2.

In portal 2, below portal 1, there should be a merged ingredient summary. in only 1 line should be the article "Olivenöl" with the amount 7 (5 + 2).

Do you have any suggestion for the solution? Thanks a lot.
