ASP Coder needed to fix business report

I have created a report for my client but there are two requirements for it that I need help with. The report runs through a list of products, as set by the user, for a rolling 15 month period, and for each month in the period it counts up the number of sales (from the sales table) and number of complaints (from the complaints table) against that product. It also calculates the percentage of complaints per sales. The total sales and complaints for the 15 month period are tallied for each item. My challenge is being able to: 1) Display the data so it can be easily copied from the web browser and pasted into a spreadsheet for further manipulation. 2) Display the average number of complaints and average percentage at the bottom of each rolling month column. I can send a PDF of the report as I would like it to look as well as the code for the report I made. Due to the confidential nature of the data, the candidate will have to replicate the associated tables with their own sample data.
