Using Combobox 1 To Filter Combobox 2

I have 2 comboboxes on a userform. In combobox1 I have a list of years which is pre-populated. In combobox2 i have some data. What i'd like to do is to sort combobox2 using the year selected from combobox1.

I have tried this slightly modified code from a different project, but cant get it to work correctly.
The code below autofilters, and selects the correct range, but will not populate the userform combobox... the highlighted row seems to be the problem:


Dim rngToCopy As Range
With Sheets("Project")
.AutoFilterMode = False
.Range("B:B").AutoFilter field:=1, Criteria1:=ComboBox6.Value
With .AutoFilter.Range
On Error Resume Next
Set rngToCopy = .Offset(1, -1).Resize(.Rows.Count - 1).Resize(, 3)
On Error GoTo 0
If rngToCopy Is Nothing Then MsgBox "No projects currently set up for the selected season!...": Exit Sub
End With
rngToCopy.Copy Destination:=UserForm5.ComboBox2.List
.AutoFilterMode = False
End With

In my data, i'd like to return columns A, B and C.
