I need to set a text box's conditional formatting so that it is displayed when
either one of two conditions in a group are selected. Let's say I have 10
checkbox choices. Two of these choices require a textbox for further info. I
want the textbox to be hidden when neither of the two are checked. A logical
OR gate.

In the conditional formatting I only have the choice to 'hide' the control
under certain circumstances, this causes a problem: If I say hide this
control
if one of the other 8 are checked and I need to check one of them and one of
the check boxes that need the text box the text box won't show up because of
the negative conditional formatting.

What I need is 'Show this control' if one of the two check boxes are checked.

Any ideas?
