It doesn't matter how you do it, but somewhere you are going to have to store the list of addresses which the user of the template will have access to. Associating those addresses with the items in the combobox and the insertion of the address so associate are the easy parts. The more difficult part is establishing which is the best method to use for your circumstances. The attached uses hard coded addresses, each line of which is separated by a pipe character '|'. Modify it to suit your requirements.
