Populate controls based on selected multicolumn Listbox item

Hello. I've read many posts regarding populating userform controls from listboxes and the below code is about as generic as you can get. The example below is for a listbox that is rowsourced in the vb properties window. I've tried other code that uses vb to source the data. The multicolumn listbox populates correctly on initialization. However, when I run the click event on my form, it has a run-time errror (could not get the list property. Invalid argument) on line #3. The combo and textbox names are correct as is the listbox name.

Like I've said, I've tried a variety of other methods found in every forum I can find, and found that the syntax seems to be correct, but I continue more often than not to get the same run-time error. I can only assume this is a problem created by how the listbox was sourced when initialized, but that to me doesn't seem like it would matter. I have been beating my head on this for days and cannot seem to figure this out. It seems so simple by looking at other posts! If there is a caveat with initialization, I can post the code used for that procedure if needed.

Private Sub Listbox1_Click()
        
        cbTextBox1.Text = Me.Listbox1.List(Listbox1.ListIndex, 3)
        txtTextBox2.Text = Me.Listbox1.List(Listbox1.ListIndex, 4)
        txtTextBox3.Text = Me.Listbox1.List(Listbox1.ListIndex, 5)

End Sub
