Multiple exposure mode D7100

I recently purchased a D7100 and want to use the multiple exposure mode but I believe something in the settings is stopping me from getting to that part of the menu as it is greyed out.
What m I missing a I don't want to reset the whole camera yet as am still learning the ins and outs of it.

Where is the mode dial set on your camera? That's the big settings dial with P, S, A, M, Auto and all that.

Page 141 in the pdf user manual covers multiple exposures. By the way, it is not available in live view.

Thanks got it figured out I had the bracketing turned on.
