Conditional Formatting Based On Field Rules Not Working

Hi diogobraga2 ,
See my top picture, save your rule as decimals, and use number.  I forget why this works this way, but there is a reason.  Something to do with percentage meaning a percentage of all your values.
Let me know if you have any questions.

If this solves your issues, please mark it as the solution, so that others can find it easily. Kudos 👍are nice too.
