Random Number Skript

[AbioticTitan947]

command /!dice <number>:
    trigger:
        broadcast "&d&l%player%&d rolled a %arg-1% sided dice!"
        set {dice_} to random integer between 1 and %arg-1%
        broadcast "&d&lThey roled a {dice_}!"

 

Can't understand this expression: 'random integer between 1 and %arg-1%' (conchshell.sk, line 38: set {dice_} to random integer between 1 and %arg-1%)

 

Why not tho (posted in help)

also when I use it it says I rolled a '{dice_}' instead of saying whatever value the {dice_} is
