Lua attempt to compare number with table (checking item on position)

[waqmaz]

I want to detect if an item is on a position or not. the script (177 line):

local redFlagPos = {x = 961, y = 1062, z = 7}
local blueFlagPos = {x = 973, y = 1062, z = 7}

local redFlagID = 1435
local blueFlagID = 4990

    if getTileItemById(redFlagPos, redFlagID).uid > 0 then
        doRemoveItem(getTileItemById(redFlagPos, redFlagID).uid)
    elseif getTileItemById(blueFlagPos, blueFlagID) > 0 then
        doRemoveItem(getTileItemById(blueFlagPos, blueFlagID).uid)
    else
        print('Fatal error nr 18!')
    end

The error:

[04/07/2016 16:15:21] [Error - MoveEvents Interface]

/edit damn, lol. I miss ".uid". I am siting at this since yesterday and have just discovered it, so sorry. Hope it will be useful for somebody.
