How do I add an extra line to a line-column chart?

Excel 2003.
I have 3 sets of numbers.
2 sets I want plotted as lines. (These are upper and lower limits of monthly
performance)
The third set of numbers is represent an actual performance; I want this set
represented as columns.
Each set is plotted monthly. (i.e.: x-axis is months of the year.)

Make a Line chart
Right click on one line in chart, use Chart type, make Column
