Not Sure What This Action Is Called

[Nursery Ed]

I am trying to achieve the following result in a form to record purchases:

1. Action: Enter an Item ID in a form.
2. Result: Have the corresponding Item Name generated for me.

I do not know the correct term for this function so Help can’t lead me to the correct solution.

Can someone tell me how this is done?

Take a look at the 'Orders' example or the 'Northwind' example both have clear examples of how to do this
