I am trying to use a tooltip to show the value at a point for a
ListLinePlot but it wont work for units.

list = {1, 7, 8, 5, 7, 3};
lista = {3, 5, 7, 2, 6, 2};

Show[
 ListLinePlot[
  Tooltip[list,
   Dynamic[{Round[#], list[[Round[#]]]} &@
     CurrentValue[{"MousePosition", "Graphics"}][[1]]]],
  PlotStyle -> Red],
 ListLinePlot[
  Tooltip[lista,
   Dynamic[{Round[#], lista[[Round[#]]]} &@
     CurrentValue[{"MousePosition", "Graphics"}][[1]]]],
  PlotStyle -> Orange]
 ]

But when i change the lists to be

list = {1 Foot, 7 Foot, 8 Foot, 5 Foot, 7 Foot, 3 Foot};
lista = {3 Foot, 5 Foot, 7 Foot, 2 Foot, 6 Foot, 2 Foot};

It no longer works.

Any thoughts?
