Modify the script + html (DotaBuff)

This is a script that shows the advantage of some heroes against others in Dota 2, based on statistics from dotabuff.com. You choose 5 (or less) heroes and see how good or bad they are against other individual heroes. I need to compare 5 heroes of one team against 5 heroes of the other team, and calculate the advantage of one over the other, automatically. Below on screenshot how it should be.
