I have a small database for receipts, there are many groups of accounts and
in each group is multiple accounts. I wish to select the 'parent' in the
first drop down box, and then have the second drop down box populated with
only the 'children' that belong to it. The lists are on a separate sheet to
the drop down boxes.

Parent Code Child
Code
travel and expences 5100 Local travel 100
overseas
200
Vehicle
300

Facilities - other 5225 Chem waste 020
general waste
50
bio waste
030

As well as this, i need the code to be brought up as well, but i figure that
I can just use a lookup function, but the first bit is proving to be easy for
the parent, but dificult for the child.
