Problem with percentage format

Hi guys,

I am trying to use the format "#,###.## %" in a Switch function but it does not work as I expected because it does not shows zeros.

I send you a picture of what I am looking for and what I am getting:

I also want that it the number is 1000% or higher, it shows the number like 1.000,00%.

How can I solve it?

Appreciate your help,

Regards.
