If I could chime in here; please don't pay anyone to solve this minor problem for you. There will be many more to come, much more difficult than this. You'll end up bankrupting yourself!
Now, upperBounds is a variable that must be defined somewhere in your code. Defining a variable is as simple as doing this:
var upperBounds = 13;
Since you don't seem to know how to define a variable, I think it's safe to assume you didn't write the code. Therefore I would ask if there is more to this code than you've posted here? I don't know what [FONT=Courier New]upperBounds [/FONT]is supposed to be doing, but looking at the graphic, [FONT=Courier New]upperBounds [/FONT]seems to be the number 13. Perhaps simply pasting the above code into your file may work, I can't say.
Please post the entire code.
Just a note. Your link is wrong, it should be: http://www.tommypowell.com/multiples.jpg
