First I inserted a 'Pivot Chart' using the 'Insert' tab left position right next to 'Home' tab...Excel asks for the range to be included and where you want the chart to be displayed...same worksheet or another one.
Then I filled out the 'Field List' which is displayed automatically...below is a picture of the way I filled out the Field List...Notice the column header lables on the Data sheet shown in orange are the fields I selected in the Pivot Table Field List. I dragged each field to the appropriate box below...
Perhaps the above will assist you.
