That looks like you're getting a back index back from the event. You should add a null check...
Instead of

selection = seriesList.GetEntry(msg.GetIndex())[msg.GetData()]

Break it into multiple statements...

list = seriesList.GetEntry(msg.GetIndex())
if list <> invalid then
    selection = list[msg.GetData()]
end if
