yeah, i cheated. I took your original reply and pasted my stuff into it.
I just missed that part. Index = price_list_tier.
I have not tried in console. just node/driver.
I haven't had issues with my other mappings, just this one. I'm assuming
because of disparate upcharges.amount types.
I see my other field at root level also named amount, but shares type of
double, which is desired.
