Hi

Im am doing a PowerPoint 2010 presentation where i want to have a dropdown combobox with the 4 different options.
My code looks accordingly:

Private Sub ComboBox1_DropButtonClick()
ComboBox1.AddItem ""
ComboBox1.AddItem "Passed"
ComboBox1.AddItem "Not Passed"
ComboBox1.AddItem "Follow-Up"

End Sub

However, my problem is that when i choose an option the dropdown list gets filled with the same options 3 times i.e. the options are trippled. (see attachment) Every time i choose an option the list gets extended further with the same options. How do i avoid this?
