Same field, different selections??

[#1]

Hi,

I am working on an application, in which I need 2 listboxes with the same field. For example 'Fruit'.

So, in listbox1 a user may select Apple ; Pear ; Banana then I want another listbox, with the same field BUT kind of unlinked to listbox1. So that in the second listbox the user may select different fruits or one, for example : Orange

I need them unlinked because I want to show a chart, with 1 bar/symbol (expression) with the fruits selected in listbox1 and another bar/symbol with the other listbox (Orange) value selected.

I'm sure I've seen this done before, but not sure how to achieve it.

Any ideas?
