How can i make it so if a person levels up that certain person gains 10 more max health?

It doesn't work this way.I have to ask u something though.Where should i put it,when i added it into the gui it didn't work have any extra ideas?

You mean like where to put the script? Try explaining more about what you mean

Yep exactly as u said i have no idea where to put that script im quite new at scripting.

Oh, is the game filtering enabled? If not, you can put that script in the workspace and make sure the Folder with all the stat's is duplicated into the player

it is filtering enabled so what should i do now? Should i disable filtering enabled or..?

If you enabled filtering enabled, you will need to use RemoteEvents or RemoteFunctions for the server to communicated to the player, and player to communicate to the server. It's only need if you want your game to not be exploitable by hackers, etc. If it is, or not, just make a script in the ServerScriptService and make it so when the player joins it duplicates a folder with all the data values

Thanks a lot! There is only 1 more thing. How can i make those health gains save like levels do?

You can use a DataStore script to save a value in the player's data, and make that value the player's health. That's how i do it though, it's easier for me.

For example: if the data value is 120, then make a script saying if the value is 120 then the player's maxhealth is 120

Thanks a lot mate! I will tell u if it works or not later i have to do something now thanks again!

Np, glad to help!, and please accept the answer.
