Nadya,

Thanks. I will take a peek at what you sent. Also, I noticed no ControlSource for listbox. I added one called MyTable. Behavior was better than before, but still flakey. I also think the dual comboboxes are confusing things, but I will need them both so I will have to figure out a better way for them to work independently of each other. Right now they are dueling comboboxes sort of.
