Meaning of てはならない

Question

ただしい じょうほう にもとづいて はっぴょう しなくてはならない

I understand that てはならない means 'must not/should not'.
However,I cannot make any sense out of the above sentence that I read in a book.
Would appreciate if someone could assist with the meaning.

What part don't you understand? It seems pretty straightforward. — ssb, Nov 29 '14 at 13:46
しなくてはならない = しない + てはならない?Is that what it means?What would this double negative translate to? — IUnknown, Nov 29 '14 at 13:49
Well, try looking at the meaning of the rest of the sentence. There's no special trickery here. You should try including this kind of information (i.e. the sentence as you understand it) in the question itself. — ssb, Nov 29 '14 at 13:56

Quite simply,

「～～してはならない」 = "You must not ~~."

「～～しなくてはならない」 = "You must ~~."

「ただしいじょうほうにもとづいてはっぴょうしなくてはならない。」 means:

"One must make a/the presentation based on correct information."
