Hi Glen,
That is easily solved. Set the Back Color property of the text box to in
the normal fashion using the fill icon in the Home ribbon. Click on the down
arrow of the icon, not the main portion of the icon. You will need to choose
"More Colors" and then "Custom". Enter 197, 236, 255 for the Red, Green and
Blue. If they are already set to that change one and change it back. Click
OK. Now go into Conditional Formatting. You will see that the fill color
button now shows the custom color. In the first condition click on the icon
itself, not on the down arrow. Click OK. That should do it.
