That would be "the" typos; or in the alternative you should have dropped the definite article from "substance."

I learned grammar by 5th grade in Oklahoma. By 7th grade we were diagramming sentences and conjugating verbs. By 9th grade we learned Latin. By 10th grade we learned Spanish. Later I learned German, French, Italian, and enough Dutch and Portuguese to get by when traveling.... But I STILL LOVE RUSH and all the other radio hosts! I scream at the radio when they make mistakes in their grammar. What is really irritating is when the grammar is concorrect on commercials and news reports, those came to the readers full of grammatical mistakes.
