Charting totals in revenue by month

Hello
I have version 2007 excel. I am having a hard time creating a chart that will take the total revenue for each month. Any help?? I have attached my excel worksheet. Thank you

Does this do what you are looking for?

Use the function in column G to extract the month from the dates in column B. Then set up the table in culumns J & K to use for the chart.
