Second input to match merge node missing

Questions
1

Fresh install of n8n, 1st workflow created (level 2 of a course). When I select to use a merge node, I get one input field (to match record), but when I drag or write 1 field in, I don’t get the second field.

Hey @povake

You should turn this on:

hi @povake, good day :waving_hand:
I would enter the same key and connect both inputs

@povake flip on “Fields To Match Have Different Names” — that gives you two separate fields, one per input. right now both inputs expect the same field name but the REST countries API returns name.common.name not customerCountry, so you need the two-field matcher.

plug your airtable creds into the Airtable node and it should match up.
