So this code works, but I don't know how to check if an enchant is already on the item, in which if it is, I would want to upgrade it from level 1 to level 2. I have started some code but not sure where to go. Pretty sure you would have to check if it contains part of the enchant, e.g. if I had Smelt I on a pickaxe, and tried to put smelt II on it would check if Smelt I is there and delete Smelt I and add Smelt II. If you have any questions don't hesitate to ask Thanks!

    if lore of {pickaxe.%player%} contains {enchant.lore.::*}
    add line 1 of lore of {enchant.%player%} seperated by " " to {enchant.lore.::*}

Secondly, if there is any way to condense the first skript please let me know
