I'm with this error in challenge 6, I've searched the forum a lot but I didn't find a solution to my problem. Apparently my process is correct.

Error:

Challenge Not yet complete... here's what's wrong:

Working on Superbadge challenge, and I'm on part 6.

*adventure package is opportunity product renamed. 

Here is what I did:
