Baertram, do you mean something like this:

Since you said you wanted Marked to be a table I'm guessing items can have more than one mark?
So you probably want something like this:


NEW Function: to check and see if an item is already marked, don't want to mark an item twice:

-- Function used to see if the item has already been marked (dont want duplicate marks in your table) --
local function FCOIsItemMarked(control, mark)
    local bIsMarked = false
    
    if ((control.dataEntry.data.FCO == nil) or (control.dataEntry.data.FCO.ItemSaver == nil)
    or (control.dataEntry.data.FCO.ItemSaver.Marked == nil)) then return bIsMarked end
    
    for k,v in pairs(control.dataEntry.data.FCO.ItemSaver.Marked) do
        if v == mark then
            bIsMarked = true
        end
    end
    return bIsMarked
end

Altered Function: FCOItemSaver_AddInfoToData(control)

1. checks to see if the control.data.dataEntry exists
2. checks to see if your myItemInstanceId exists
3. loops through your marked Indices from 1 to gFCONumFilterIcons
4. checks to see if the myItemInstanceId exists in your markedItems[markedIndex] table
5. checks to see if the item control.dataEntry.data.FCO.ItemSaver.Marked table already has the mark in it to avoid duplicates
6. checks to see of the tables exist, if not it creates them
7. last, inserts the mark into the table

local function FCOItemSaver_AddInfoToData(control)
    if ((control ~= nil) and (control.dataEntry ~= nil) and (control.dataEntry.data ~= nil)) then
    local myItemInstanceId = MyGetItemInstanceId(control)
        if (myItemInstanceId ~= nil) then
            debugMessage("[FCOItemSaver_AddInfoToData] ItemIstanceId:" .. tostring(myItemInstanceId))
            --Check if the current item is marked with any of the marker icons
            for markedIndex=1, gFCONumFilterIcons, 1 do
                if markedItems[markedIndex][myItemInstanceId] and (not FCOIsItemMarked(control, "Mark"..markedIndex))then
                    --if the table doesn't exist create it --
                    if control.dataEntry.data.FCO == nil then 
                        control.dataEntry.data.FCO = {}
                        control.dataEntry.data.FCO.ItemSaver = {}
                        control.dataEntry.data.FCO.ItemSaver.Marked = {}
                    end
                            
                    table.insert(control.dataEntry.data.FCO.ItemSaver.Marked, "Mark"..markedIndex)
                end
            end
        end
    end
end
