Prevent Error Messages in Results Column: Display Blank Instead

How do you stop error messages from appearing in a results column? It's supposed to present a personal intro, but says various messages now and again. One example is: I apologize, but I am unable to generate a personalized email intro since the provided links appear to be inaccessible or return "Not found" errors. Without being able to verify specific company news or developments, I cannot create an accurate and meaningful introduction. I need it to leave the cell blank instead.
