You can create a button from the Userforms list, and associate the
macro to this button. Go to Tools>Customize>Forms. Select "Forms" and
this will add all Userforms to the toolbar.
Now you can click on the button symbol and create the button on the
spreadhseet. Then right click on the button to find a bunch of
options, including how to assign a macro to this button.
Hope this helps.
Joe.
