I'm guess you mean "you're vital", not "your vital". As in, someone told you "you are vital", and not "your vital [something]", like "your vital cat is annoying". Look up the difference between the words "you're" and "your". While you're at it, learn the difference between "it's" and "its". Ok, end of my rant.
Anyway. Assuming you mean to say that someone told you, "you're vital", it means you are needed. You are vital to this project. Money is vital to paying your bills. Water is vital for surviving. Hopefully your significant other will tell you, "You are vital to my existence."
There are a few other contexts of the word vital, but this is probably the one you're curious about. Go to www.dictionary.com and key in "vital" to see what I mean. Best of luck!
