How Do I Update A Value Via The Server Whilst Adding To It

Help and Feedback Scripting Support

For my game’s quest system, I am required to update the player’s quest number via a server script so that it can be saved in a datastore. My issue is that I have a remove event to update any value to anything, except I cannot figure out how I would make it add or subtract from the instance’s current value.

game.ReplicatedStorage.Events.Misc.UpdateValue("QuestNum", *add 1 to the current value*)

if you have a function to get the value just get that and add or sub to that, you could also do it internally
