hi,

I'm trying to write code that will:
1. calculate the percent difference of 1 item against a list of 70 other items,
2. then select any item that is between 1% and 5%,
3. then list those items

Is this possible?

You can do all this with formulas and filtering. Why do you need code to do it?

Your question is: Is this possible?
The answer is: Yes, it is possible to do so.
