Add New record and auto populate unique (required) field from parent

Hi,

I have successfully linked applications and master details forms so that they capture the unique field and deliver required results.
If I have an editable grid (multiple) it provides me with the correct data.
If I want to add a new record, I select “Add new”. I want the blank table to automatically assume (capture) that I am adding a record against the parent
e.g, I search “bedroom 1”, it provides me with a table of all furniture in bedroom 1 already identified. I forgot to add TV to the room, I select “add new” , i now need to re-type in Bedrrom 1. How do I automate this.

I’m not a developer, go easy on me…

TIA

You have to create a new form to handle creation of the new record. Add a parameter of the unique key in that form. Call that form using button in the master form, passing the unique key information.
