I have a working userform that I would like to make more user-
friendly. Four option buttons, a text box, OK and Cancel buttons.

I want the user to be able to press enter from the option button that
has the focus and go straight to the textbox without tabbing through
all the other option buttons. Ideally, pressing enter would
automatically "click" that option button but I'm ok with using
spacebar. Then, pressing enter from textbox1 still needs to activate
the OK button (as it currently does). I thought it would look
(partially) like this:

private sub optionbutton1_enter( )
textbox1.default = true
end sub

private sub textbox1_enter( )
commandbutton1.default = true 'commandbutton 1 is the OK
end sub

the error message I get when I run the form reads "Could not set the
default property, member not found." in regards to the option
button_enter, even if I comment out the textbox1_enter section. What
should I be trying?
