Where can I find a map of the distribution more closely than this?

They obviously want a seat in sections F1, 2 or 3, but can not find a table that tells me what to write or the number of lines of Sectines departure. For example: I buy tickets for a concert tomorrow, and if I draw the line J, I do not know if I go back to putting them in more than one seat or maybe start with lines J and Front Row? See what I mean ... :) Thanks
