I just re-read your original message and see you used an OptionButton from
the Form's toolbar... I'm pretty sure you can't change the font properties
on that type of control. Now, if you use an ActiveX OptionButton from the
Control Toolbox toolbar instead, then you can use this event code (it goes
on the worksheet's code window, *not* in a general Module) to make the font
bold whenever the OptionButton is selected...
Private Sub OptionButton1_Change()
With Sheet7.OptionButton1
.Font.Bold = .Value
End With
End Sub
Change the Sheet7 reference in my example code to the actual sheet name the
control is on.
