Hi, hope for some simple advice...

I am creating a classical dynamically linked form, which populates in response to other control fields, based on Comboboxes.

However, on closing a form I want to depopulate the comboboxes, and effectively clear the form, but I'm unsure how to achieve this. The problem I'm having is that obviously none of the entries in any of the comboboxes are "", so it won't let me specify no contents. Any suggestions appreciated.
