check if variable changed not triggered

[woven orchid]

    dollars.Changed:Connect(function()
        print("Dollars changed")
        sessionData[player.UserId].Dollars = dollars.Value
        print(sessionData)
    end)
    

everytime i run the game and change the dollars variable in the explorer the dollars.Changed thing doesnt get triggered. is there a reason why this happens?

it depends on the side you are changing the value from

when you press "play" you have the option to either be on the server side, or on the client side (you play as your character)

i assume what happened is that the script is not a local script, and when you changed the value on the client side, the server didnt see that (it cant)

oh true, but why did it work in this video if it shouldnt work?

its also a serverscript but it somehow detects the changing variable

because in the clip

he said

"we go into the server"

and he switched to the server side
