Ok, it's not that simple ...
Because the JSON doesn't bring the 3 data that way.
Sorry for not giving the data all together, I thought it was going to be confusing to understand, and I thought that what I wanted to do was simpler.
Each JSON (for each X) brings 3 arrays, of which each one brings 4 objects, and I have to take object "4" from each array as an index.
In the JSON they are the same object in different arrays. I do not know if it is well understood.
Something like that...
X0 -> JSON [ ["111","112","113","114"] ["121","122","123","124"] ["131","132","133","134"]]
X1 -> JSON [ ["211","212","213","214"] ["221","222","223","224"] ["231","232","233","234"]]
..
..
X5 -> JSON [ ["511","512","513","514"] ["521","522","523","524"] ["531","532","533","534"]]
So in each X loop I have to enter in different Y, 3 different values X0 (Y1, Y2, y3) ... X5 (Y1, Y2, Y3) where each Y are the values that end in 4...
In the JSON they are the same object in different arrays. I do not know if it is well understood.
If you can solve this I will be eternally grateful
