Although I have little knowledge of VBA and bow to your wealth of knowledge on the subject, it would appear from the results that I am getting that gmaxey's suggestion is not far off.

The first screen capture shows what is obtained if all the options in ListBox1 are selected (results appear as required in TextBox2). You will note that the first selection (or the one highest up the list if less is selected (see second screen capture)) from ListBox1 is repeated each time.

If I leave out the wish for the items to be shown in TextBox2 as they are selected from ListBox1, is what I request still possible?

Thanks!
