Ok but i still get lua errors and a strange behaviour of my bar:

function()
    local value = select(8, UnitBuff("player", "Blutschild")) or 0
    return value;
end

So with this i get the expirationTime and i return it. My goal is
to have a bar which shows when the buff will expire.
With the above code i just get lua errors.
