Populate Combox1 dropdown, click OK and insert value on page.

Hi, I have this for populating a dropdown box but when I execute it the dropdown is empty. I think I have to add something to the change method but not sure what. 

Also, when user hits "OK", the option selected needs to be inserted multiple times on the document at specific X and Y (several labels on document). 

Private Sub ComboBox1_Change()

UserForm_Initialize

End Sub

Private Sub UserForm_Initialize()

'Populate ComboBox with Options

ComboBox1.AddItem "option 1"
ComboBox1.AddItem "option 2"
ComboBox1.AddItem "option 3"
ComboBox1.AddItem "option 4"

ComboBox1.ListIndex = 0

End Sub

Private Sub Ok_Click()

End Sub
