"Nemusíte tady být."

Translation: You do not have to be here.

What's wrong with "You must not be here"? This version was not accepted.

[VladaFu]

It means something completely different. Like "You are not allowed to be here."

[SerhiyBila]

Thanks! And what should I say to a person who really must not be in some (for example, dangerous) place?

[VladaFu]

Nesmíš...

[strubkin]

Why not "you have not be here"?

[VladaFu]

This is wrong English syntax. "You do not have to" is how you say one does not have an obligation.
