problem with pick and shovel

[Dogrinha]

Hello, my players are not able to open holes with pick or shivel if there are fluids on top of the hole, how can I open even with the fluids?

unction onUse(cid, item, fromPosition, itemEx, toPosition)
    if((itemEx.uid <= 65535 or itemEx.actionid > 0) and isInArray({231,9059}, itemEx.itemid)) then
        doTransformItem(itemEx.uid, 489)
        doDecayItem(itemEx.uid)
        doSendMagicEffect(toPosition, CONST_ME_POFF)
        return true
    end
local newPosition = {x=33356, y=31180, z=8}
if(isInArray(HOLES, itemEx.itemid)) then
