You need to create a sub for the initialization of the userform that will fill the list of combo boxes at the start. Example of filling the combo box full of all the countries in the world is as follows:
Private Sub UserForm_Initialize()
Dim vaCountry As Variant
vaCountry = VBA.Array("United States", "APO/FPO", "Canada", "United Kingdom", "Afghanistan", "Albania", "Algeria", "American Samoa", "Andorra", "Angola", "Anguilla", "Antigua and Barbuda", _
"Argentina", "Armenia", "Aruba", "Australia", "Austria", "Azerbaijan Republic", "Bahamas", "Bahrain", "Bangladesh", "Barbados", "Belarus", "Belgium", "Belize", "Benin", "Bermuda", _

"El Salvador", "Equatorial Guinea", "Eritrea", "Estonia", "Ethiopia", "Falkland Islands (Islas Malvinas)", "Fiji", "Finland", "France", "French Guiana", "French Polynesia", "Gabon Republic", "Gambia", _

"Hungary", "Iceland", "India", "Indonesia", "Ireland", "Israel", "Italy", "Jamaica", "Jan Mayen", "Japan", "Jersey", "Jordan", "Kazakhstan", "Kenya Coast Republic", "Kiribati", "Korea, South", _
"Kuwait", "Kyrgyzstan", "Laos", "Latvia", "Lebanon", "Liechtenstein", "Lithuania", "Luxembourg", "Macau", "Macedonia", "Madagascar", "Malawi", "Malaysia", "Maldives", "Mali", "Malta", "Marshall Islands", _

"Tuvalu", "Uganda", "Ukraine", "United Arab Emirates", "United Kingdom", "United States", "Uruguay", "Uzbekistan", "Vanuatu", "Vatican City State", "Venezuela", "Vietnam", "Virgin Islands (U.S.)", _
"Wallis and Futuna", "Western Sahara", "Western Samoa", "Yemen", "Yugoslavia", "Zambia", "Zimbabwe"
cbCountry.List = vaCountry
End Sub
The userform's combo box name would be "cbCountry". You could have multiple combo boxes with differnet names and fill them all with whatever items you wanted.
Hope this helps!
