Problem with targeting

[Count Dracula]

Hello guys

I need to use a vial of blood on a tile and if I have one storage, it will remove one tile and summon a monster.
But if the player uses the blood without the storage nothing happens, but creates a pool of blood over the tile.

My problem begins now. Because the pool of blood is over the tile, the player with the storage can't use the vial of blood on the floor with the action id, and continue the quest.

My script of the vial of blood is as it follows:

            elseif target.actionid == 62997 then
                local lordvampire = Tile(lordVampirePosition):getItemById(9242)
                if not lordvampire then
            return true
                end       
                                
                local vampire1 = Tile(vampire1Position):getItemById(9239)
                if not vampire1 then
                return true
                end
                vampire1:remove()
                
            
                local vampire2 = Tile(vampire2Position):getItemById(9239)
                if not vampire2 then
                return true
                end
                vampire2:remove()           
            addEvent(clearMob, 2 * 60 * 1000, Position(32937, 31457, 2), Position(32943, 31464, 2), 'vampire bride', Position(32939, 31459, 2))       
            Game.createMonster('vampire bride', Position(32939, 31458, 2))
            Game.createMonster('vampire bride', Position(32941, 31458, 2))   
                    addEvent(Game.createItem, 2 * 60 * 1000, 9239, 1, vampire1Position)
                    addEvent(Game.createItem, 2 * 60 * 1000, 9239, 1, vampire2Position)
            end
