MoneyGui.Text = Money.Value
So basically if you were to just do script.Parent.Text = Money then you wouldn't be returning anything, by putting the value in there, you are basically returning the VALUE of the money variable, for example if a player had 300 money, it would do 300, if you had just done script.Parent.Text = Money, you would get an error
Hope this helped!
Value is Money.Value. The value of money is Value
