Hello One way to set this up would be to create a new data type called “Service”. Within the Service data type could be two fields: “Name of Service” (Type: Text, List: No), and “Price” (Type: Text, List: No).
Then you can create a field within the User data type called “List of Services” (Type: Service, List: Yes).
This way, a User can create a new Service with inputs (Input Name of Service, Input Price of Service) and click ‘Add’. When the Add button is clicked, the workflow could be:
Data --> Create a New Thing --> Thing: Service, Fields to Change: [Name of Service = Input Name of Service’s value] and [Price = Input Price of Service’s value].
Then create a second action in the workflow which adds that Service to the User’s List of Services. The workflow could be:
Data --> Make Changes to a Thing --> Thing to Change: Current User --> Field to change: List of Services add (Result of Step 1… Create a New Service).
