Hello Thias08

Could you specify which number are you talking about ? you mean your amount of money in game, on the left bottom ?

they r item pretties no u can set items like bike or mounts for quick use

Oh yes. So these numbers are shortcut on which ones you can define an item you often use. Like your mount or you fishing rod.

Just drag and drop the item you want from your bag, as showed on the gif (it needs to load for few seconds).
