Combobox selection unable to cascade values from Access database table

sorry but i need the help badly. i'm trying to cascade values from an access table (db1.mdb) which contains 4 informations. let's call it A, B, C and D. In excel, i made a userform which enables the user to choose from combobox1 then cascade that value to combobox2 and so on and so forth.

for instance:

combobox1 = A, then combobox2 = B... and so on

I saw a few post similar to this but using a table from excel sheet. my data is coming from an access table. i have already initialized the values under A but how to proceed on the selection is my problem.

Set Db = OpenDatabase(DBpath, False, False)
Set rs = Db.OpenRecordset("myTable", dbOpenTable)

With rs
If Not .BOF Then .MoveFirst
While Not .EOF
userFTEST.ComboBox1.AddItem .Fields(0)
.MoveNext
Wend
End With

rs.Close
Set rs = Nothing
Db.Close
Set Db = Nothing
here's the code i'm starting with but could not produce the way i want it..

Private Sub ComboBox1_Change()

x = userFTEST.ComboBox1.ListCount
If x >= 1 Then
For i = 1 To x

If userFTEST.ComboBox1.List(i - 1) = userFTEST.ComboBox1.Value Then
GoTo NextStep:
End If
Next i

MsgBox "There is no MATCH!"
userFTEST.ComboBox1.SetFocus
Application.ScreenUpdating = True
Exit Sub
End If

NextStep:

"i can't seem to put the lines here"


End Sub

Appreciate if someone could help. it's very important as i'm running out of time.



Thank you all!
