Dependent and Non Dependent Comboboxes

Cascading combo boxes have been done online and I had a problem recently which knocked me for 6 as we say here in Australia. Anyone who deals in cascading combo boxes will know only too well that if you are using a list and the Indirect formula to manage the combo boxes then the process can get very unruly very quickly. One of the issues with comboboxes is that they are set up to work in sequence. Combo box 1 feeds into combobox 2 which feeds combo box 3. The combo boxes need to be filled out in that order.
