How can I put the djns on scrolls that are not free?

[Jpstafe]

Hello otland community, my question is how can I make sure that the djns are not free, that they are by scrolls... I already have the scrolls made, but when I go to the djns I can still pass the doors, without activating the scrolls
Scroll Blue djns:

function onUse(cid, item, itemEx, toPosition)
 
local pos = getCreaturePosition(cid)
if (getTilePzInfo(getPlayerPosition(cid)) == TRUE) then
if(getPlayerStorageValue(cid, 1015) == 1) then
doPlayerSendTextMessage(cid, 22, "You already have Blue Djin Quest!")
else
doRemoveItem(item.uid, 1)
setPlayerStorageValue(cid, 1015, 1)
doPlayerSendTextMessage(cid, 22, "You just completed Blue Djin Quest!")
end
else
doPlayerSendTextMessage(cid, 22, "You can only use this item inside protection zone!")
end
return true
end

Scroll Green djns:

function onUse(cid, item, itemEx, toPosition)
 
local pos = getCreaturePosition(cid)
if (getTilePzInfo(getPlayerPosition(cid)) == TRUE) then
if(getPlayerStorageValue(cid, 1038) == 1) then
doPlayerSendTextMessage(cid, 22, "You already have Green Djin Quest!")
else
doRemoveItem(item.uid, 1)
setPlayerStorageValue(cid, 1038, 1)
doPlayerSendTextMessage(cid, 22, "You just completed Green Djin Quest!")
end
else
doPlayerSendTextMessage(cid, 22, "You can only use this item inside protection zone!")
end
return true
end
