if you want it disabled always, you can do that in the userform
properties.

if you want it disabled due to a certain condition when the userform
opens, you can do it programatically in the userform_initialize sub

if xxxxxxxx then
optionbutton1.enabled=false
else
optionbutton1.enabled=true
end if

where "xxxxxxx" is your condition.
hope that helps.
