Hello all you clever people!

Been having some success with listboxes to collect data on Userforms, but
what I would like to try and do now is have a multi colum listbox, ie I have
the main selection of a "Business Unit" which depending on the choice made
will offer up a list of "Business Area", again depending on the choice made
here then a list of "Departments" to be shown. Is it possible to do this,
can anyone point me in the right direction?
