Microsoft Access (2007-2016) - Form List Box Can't Be Found In Current Record?

I'm currently using Microsoft Access file format "Access 2007 - 2016". What I'm trying to do is make a form with a combo box, that when a value is selected will populate a list box with results. I have a table with multiple fields, but two relevant ones specifically. The combo box has all possible names that could appear in Field A (drawn from a separate table), and the list box needs to display all values from Field B that correspond to the chosen name. Not all names from the combo box have a corresponding Field B value, and some names have multiple corresponding Field B values. So far, I've got a macro that runs after the combo box is updated. The macro uses the OpenQuery action, then the Requery action directly after. My current problem resides in this Requery action. When I run the macro, I get an error stating that "There is no field named 'List Box A' in the current record." It also gives the error number: 2109. For the Requery's Control Name, I've triple checked that it's the same as the name shown in the list box's property sheet. What am I doing wrong?
