I've read your description and your modified code several times, and I'm still at a loss to understand what you are doing. And the output from your code does not clarify it for me.

A wordful description -- something more than "I need to return the sum of the elements of each combination of the arrays. " and maybe a worked example might clarify things and get you more useful responses.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.

The start of some sanity?
