VBA for MS Access

I am working with Access 2010 and need some help periodically with the VBA code as the Help system must have been written by someone who had better things to do. Am I in the right group or is there a VBA group? IF I am in the right group how do you add data to a ComboBox with 2 columns. I can add data in the first column but not the second column. I have seen some code saying create a string with ";" between strings and then use the recordsource property. I can't get it to work. Any help would be appreciated. Windows Vista.
