Use id from one table to update record in another

Kia ora!

I’m trying to set up an automation so that when a record is created in one table, it updates a record in a second. Both tables are in the same base.

Here’s the update step of the automation:

Both tables have a name field, and entries in the first table (which is being watched for new records) will have names that match records in the second table.

I think what I’m missing is what to put in the record id field of the update step - I’ve put the name field from the trigger but am getting an invalid inputs error message.

Any thoughts? I know something like this is possible with a third party automation app, but I’m keen to keep it all in one place if possible!

Edit: figured it out! I was missing a find records step.
