database drill down

Last Modified: 2010-05-03
I have an access form that uses drill down or cascading combo boxes and/or list boxes to selectively narrow down choices, they use the following code.
for example.
    cbosize.RowSource = "Select tbldata.size " & _
        "FROM tbldata " & _
        "WHERE tbldata.style = '" & cbostyle.Value & "' " & _
        "and tbldata.species = '" & cbospecies.Value & "' " & _
        "group BY tbldata.size;"
This works fine if you select the combo boxes in sequence.
after having made selections in each combo and reaching the last selection in cbosize, is it possible to code it such that the user can go back to the first combo cbostyle
change the value and not have to reselect the original choices?  That is to say that the original values  selected do not have to be reselected if they are valid choices
based on the value that has been changed.
