Using Checkboxes to Select Other Checkboxes

I created a userform that has checkboxes arranged like this:

[]All Days []Weekdays Only []Other

[]Monday []Friday
[]Tuesday []Saturday
[]Wednesday []Sunday
[]Thursday

And a command button.

What I want is to be able to:
-Click "All Days" and all of the days be selected
-Click "Weekdays Only" and only have "Monday"-"Friday" selected
-"Other" Turns all other boxes to "False"
-If you manually turn all days to "True", then "All days" is automatically set to "True"
-If you manually turn Monday - Friday to "True", then "Weekdays Only" is automatically set to "True"
-If you choose any other configuration of days, then "Other" is automatically set to "True"

Thanks!
