Backpack system not working

I tried creating this backpack system but it’s not working.The youtube video that I saw told that I had to put the name of the script that gives points.But I can’t figure out which one of them gives the Hydration.Could you guys help me

The line that gives the hydration points is:

player.leaderstats.Hydration.Value = player.leaderstats.Hydration.Value +5 * (player.leaderstats.Rebirths.Value)

Yep but the youtube video says that I have to put the scripts name but I did but it did not work

You are being very vague here. I cannot understand what you are trying to achieve…
