Not sure what you are asking ......if I enter in 10 Tables you want the form to generate a table number from 1-10 and then a seat
number at that table?
Yes, if you enter 8 in the table field and the table seats 10 then I need to generate a table number and the the seat number. in this case will have 8 tables and 80 seats.
What if you generateed a series of random numbers from 1 - 80 and put them in an array. Then as each person came to register you woudl grab the random number off of thetop of the array and assign them the table and seat accordinngly.
