Help with combobox on form

[JenniferMurphy]

I have a very simple database. It has just 2 data tables and 1 junction table. I am trying to create a form for data entry. I cannot get it to display more than 1 value.

I put the accdb file on this Onedrive folder.

Firstly you had the sub form as Single form?
Secondly, you would need an autonumber in your junction tabke.

Then you need to add records in the subform?
