I can't figure out how to set up my form so it works the way I want. I am creating a data entry form and I would like to have my child subform control (IDChild) to be auto filled with the parent control (IDParent) when it is entered. Also, I would like to keep the subform filtered by what is entered in the parent control. Hopefully someone can help me. I am sorry but I can't attach the database. Just FYI, I used the subform wizard to add a subform to the form (using parent table) I already created. Thank you for your help.
