How to Sync Labels in Realtime for Overlays + Number Min/Max with the new Label System?

I need help to setup a Label that displays Money via a Number Variable with the type Player Persistent.

Label Sync between Variable and Label is already done, but I'm stuck with the Label to show only Numbers between 0 and an Upgradable Max Value.

So that if you try to get a Value under 0 in the negative Numbers it will automatically set to 0 and that also for the Maximum Value.

How could you do that.

IMPORTANT: I use the new Label System where you can use Procedures to get the Value by using the Return Block!
