I have a subform that I want to link to a list on main form, and If I change the value in list, then the content of subform should be changed to, how can I do this job?
回答1:
CLick on your subform frame and use the link properties:

The Link Master Fields
should be your listbox, and the Link Child Fields
should be its corresponding foreign key field in the subform.
