not prepared to download from google, only uploaded files. remove forms/reports/tables/queries not relevant to your question, compact then zip using the upload facility (click on the go advanced button at the bottom of the window)

What you describe is cascading or dependent combobox/listbox - common topic.

Code needs to Requery the second combobox or set its RecordSource property. Post your code behind Owners.

Why is Cultivars combobox a query that joins tables? Why is Query missing a space in front of FROM?

If you want to provide files, follow instructions at bottom of my post.

Thank you for the assistance. To get he IP Owner's name with their rspective IP Owners code, two tables are joined. Thats why Cultivars is a query that joins.

SELECT     Plants.PlantID,
    Plants.Cultivar,
    Plants.IPOwner,
    Profile_Display.Display AS [IP Eienaar],
    TblLicence.ConType,
    TblLicence.Renewable
FROM 
    (TblLicence
    LEFT JOIN Plants ON TblLicence.PlantID = Plants.PlantID)
    LEFT JOIN Profile AS Profile_Display ON Plants.IPOwner = Profile_Display.Nr;
