Thanks Massimo! This seems to work!

Anyway, would it be possible to use a single function so that I don't have to use many Peeks?

Or this is the best way we could use? Thanks!!!

You can achieve this in a straight table with only one function. Although, it seems that you wanted to accomplish it in the back-end:
