Macro code to change cell range to named range

I need to change my macro code so the macro will use a range based upon a name I've given it (insert -> Name->Define), instead of a fixed cell range. Currently my code is as follows:

Private Sub ComboBox10_Change()

Application.ScreenUpdating = False

Select Case ComboBox10.Value
Case "0"
Rows("754:817").EntireRow.Hidden = True
Case Else
Rows("754:817").EntireRow.Hidden = False
End Select


End Sub

The range in the sample is 754:817. I need it to just look up a name range that has those cells, like the range list1, for example. Any help is appreciated.

If you don't understand what I'm asking for then please reply and I'll clarify.
