Can someone tell me what is the difference between "¿Qué te pasa'" vs "¿Qué le pasa'"
The former is "familiar" (tú form) and the latter is "formal" (usted form). If you're not sure about what those mean, you might want to do a search of the forums. There are plenty of threads dedicated to that subject.
If you still don't understand, post again, and maybe someone can explain it to you in more detail.
