HI, well in your situation, it would be better to place those values into a host / list table or some other SQL table and then use SQL driven option to pull those values into the combobox. That way, you can use dependent drop down list such that a user chooses a response from combo1, it will display combo2 with the values except for what is picked in combo1,etc.
This is the only way I would know how to do it. -- David
