Can someone help with this Spanish translation?

I'm having some trouble with this particular sentence i need to translate to English.. It just feels really complicated grammatically:

"Didn't you know what you had to do as gang-members?"

A simple (but correct) translation would be very much appreciated, as i'm really stuck..

No sabías lo que tenías que hacer como un pandillero?

The plural for gang members suggests you are talking to more than one person. If so,
Ustedes no sabían lo que tuvieran que hacer como pandilleros?
Otherwise
No sabías lo que tuvieras que hacer como pandillero?
