Hello friends, when running this code, it gives an error. No matter how much I think, I don't understand how to remove this error.
Can anyone help me?

What I have tried:

I expect this code to show me the price difference between decentralized exchanges, and I compiled the code in javascript online and remix environment, but it gives an error.

"when running this code, it gives an error."
What error, and where does it occur?

"It doesn't work" is probably the most useless problem report we get - and we get it a lot. It tells us nothing about what is happening, or when it happens.
So tell us what it is doing that you didn't expect, or not doing that you did.
Tell us what you did to get it to happen.
Tell us any error messages.

Hmmm... That tends to happen when using someone else's code or if asking ChatGPT to write it for you.

At a guess it could be the fact that you create two variables named decima10 (decima-one-zero) and decima11 (decima-one-one), but then try to use two variables named decimal0 (decima-ell-zero)and decimal1 (decima-ell-one).
