Help with some coding I can't seem to configure

[TheOldSouls]

I'm Trying to make an addon that can return to me values of how much total artifact power I have across all my weapons on a given character, however I want to use the LibArtifact addon information in order to return these values (since from what I gather without using anything else you can only return information on one weapon at a time). If anyone can help me with this i'd be very appreciative. I am fairly new to this stuff and this is the first time I've really ever tried. If I need to put some code snippets up for what I have so far, just let me know and I can.

Thanks ahead of time!

Here is code to get the in-bag artifact data

for i = 1, NUM_BAG_FRAMES do
    for j = 1, GetContainerNumSlots(i) do
        if select(4, GetContainerItemInfo(i, j)) == 6 then
            SocketContainerItem(i, j)
            print(C_ArtifactUI.GetArtifactInfo())
            ArtifactFrame:Hide()
        end
    end
end

Thanks! That's what I couldn't figure out.
