Database :: Possible To Have More Then One LabelField In Flex?

I have a combo box that is currently getting its information from a database this seems to be working fine.Now I would like to have content from two fields displaying in the combo box at once. Say First Name & Last NameI've added the information to the query fine but the data displayed in the combo box seems to be controlled by the labelField property and it seems to only allow one variable at a time. So it will either display First Name or Last Name but not both at once.here's bit of my code

private function NameData():void { //NAME DATA
var stmt:SQLStatement = new SQLStatement();
stmt.sqlConnection = sqlConn;

[code].....
