Keep focus on the Mainform when making selections in a Subform


I have a series of checkboxes contained in an “Item Replica” table (which parallels the systems “Item” table). On the Item Card I have included a subform Materials Tab which contains the boolean fields that need to be selected. However once the selection is made the focus remains on the subform and the user has to click back on the Item Card in order to continue scrolling through the items. Is there any way to either keep the focus on the Item Card or direct the focus back to the Item Card once the selection is made?

Thank you.

Alright, I sidestepped the problem by coding a Boolean Global Variable on the Item Card to provide the same functionality as the boolean fields in the subform.
