hp/mp missmatch

// run only by the merchant, who delivers potions to the farmers
function buy_potions(){
    var mp = potion_types[1];
    var hp = potion_types[0];
    var stack = potion_types[2];
    // if we have enough gold to purchase, and we need at least one potion
    if(character.gold >= parent.G.items[hp].g && (stack - quantity(hp)) > 0){
        // we buy enough potions to top off and meet the stack amount
        parent.buy_with_gold(mp, stack - quantity(mp));
    }
    // if we have enough gold to purchase, and we need at least one potion
    if(character.gold >= parent.G.items[mp].g && (stack - quantity(mp)) > 0){
        // we buy enough potions to top off and meet the stack amount
        parent.buy_with_gold(hp, stack - quantity(hp));
    }
}

needs to be

// run only by the merchant, who delivers potions to the farmers
function buy_potions(){
    var mp = potion_types[1];
    var hp = potion_types[0];
    var stack = potion_types[2];
    // if we have enough gold to purchase, and we need at least one potion
    if(character.gold >= parent.G.items[mp].g && (stack - quantity(mp)) > 0){
        // we buy enough potions to top off and meet the stack amount
        parent.buy_with_gold(mp, stack - quantity(mp));
    }
    // if we have enough gold to purchase, and we need at least one potion
    if(character.gold >= parent.G.items[hp].g && (stack - quantity(hp)) > 0){
        // we buy enough potions to top off and meet the stack amount
        parent.buy_with_gold(hp, stack - quantity(hp));
    }
