A message gets received by an On Message trigger! Ever! You cannot expect by copying some source code lines of an OnMessage trigger that those leads to the right results in a different trigger function. The parsed parameter values aren’t available in all functions at all times. Please evaluate a received message in an On Message trigger. Store evaluated values in labels. Evaluate those label values in On Entry trigger of pm_3.
