What does "你让我开心!" mean?

Question:

DON'T USE GOOGLE TRANSLATE. If I wanted to Google Translate it I'd do it myself.

Answer:

With numerical pinyin, "Ni3 rang4 wo3 kai1xin1"

Traditional characters (妳讓我開心--I have to put it in Traditional Characters to translate it as t.c. corresponds with Japanese)

Literally it means, "You yield me happy." However, that makes little sense. So, a more commonly spoken way in English would be "you make me happy."
