How do I make upgrades in my clicker game?

I'm trying to make a simulator game where if you click a button it gives you 1+ in leaderstats, it works fine but.

How do I make upgrades? Like a script that automatically runs and changes the player's click for cash from 1+ to 10+.

I'm not a very good scripter, and I can't seem to figure out how to do this.

I'm using remotes to do this. (remotes to give the cash)
