Access Database Help

Hey guys - was wondering if anyone might be able to help
I'm building a database in Access (no moans, please) at work and I'm wondering if anyone had a quick fix for this: The main data entry form has a whole load of drop down lists and next to each is a button to open an 'add new' form which adds a new item to the list. This all works fine, but the problem is that after you add a new item it saves to the table but doesnt appear in the list until you close the whole form and open it again. Is there a way to get the form to refresh on its own (really dont wanna make it a refresh button - the users at work aint all that clever)? Any help would be welcome!
