I have two option buttons (from the Control Toolbox in Excel 2003) named
"OptionButton18" and "OptionButton19", both of which have the GroupName
"nameWallTile."

OptionButton18 also has what I am considering a subgroup of 3 option
buttons, all of which have the GroupName "nameWallTileBKSP"

I would like the group "nameWallTileBKSP" of OptionButton18 to be disabled
when OptionButton19 is selected.

Any suggestions? I'm not very familiar with VB, but am not afraid of
learning something new, especially about Excel!

Thanks!
