Classic hide rows if cell value is zero - not working, please help!

I have drop downs on another sheet that control cells so that if the drop down is the same as the value next to the cell it shows a 1 if not a zero.

I want to hide the rows that contain cells with a zero and have read forum answers but for some reason this isn't working. It comes up with Error 1001 object defined or application defined error and highlights

"Rows(rCell).EntireRow.Hidden = True".

Or says my argument isn't optional.

I would also like to expand this and hide irrelevant columns as well once this is cracked.

Private Sub Worksheet_Change(ByVal Target As Range)
         
 Dim rCell, rRange As Range

    For Each rCell In Range("B10:B921")
        
        If rCell.Value = 0 Then
   
            Rows(rCell).EntireRow.Hidden = True
            
         End If
     
         If rCell.Value = 1 Then
         
            Rows(rCell).EntireRow.Hidden = False
          
         End If
        
        Next

End Sub

Any help is appreciated.

Thanks
