I have a repeating section in a modern form that I would like to populate with other key data.

I am able to connect the Currency dropdown and have then created variables to populate the remaining fields.

lookup("Purpose Trust Bank Details","ID",[Form].[Repeating section 2].[Current row].[Currency],"Account Name")

I have then created a Repeating Section rule to update the fields when Currency is filled but nothing is populating so not sure what I have done wrong.
