Use a userform to pass values from combo box to autofilter with custom filter for dates

Hi all,

I have a problem passing a value from a cell into the custom filter in autofilter.
Can some one pleases look at the below code and let me know where I go wrong? (the criteria for field 2 works as it should).

Sub SelectionFilter()

    Rows("6:6").Select
    Selection.AutoFilter
    Selection.AutoFilter Field:=2, Criteria1:=Range("B3")
    Selection.AutoFilter Field:=1, Criteria1:=">=" & Range("C3"), Operator:=xlAnd, Criteria2:="<=" & Range("D3")
End Sub

Thank you in advance.

Greetings.
