I have a front menu page in my publication and using the option 'Go to Page <random>' works fine to choose a page from two other pages in the same chapter.

However what I'd like to have is:

Option 1 in the Menu (Page 1) - Selects at random Page 2 or Page 3
Option 2 in the Menu (Page 1) - Selects at random Page 4 or Page 5
Option 3 in the Menu (Page 1) - Selects at random Page 6 or Page 7, and so on

I understand that 'random' works on the basis of pages in the same chapter. I can't find a way to select a given number of pages to be included in one particular random option, ignoring other pages in the same chapter. I could place pages 4 and 5 in the next chapter, but that would then be in a different chapter to the main menu. Is it possible to achieve the required selective 'Go to Page <random>' as outlined above?

I'm using Opus Pro 9.02 on Windows 7.

Thanks

There's a profile link at the top right - you can add your Opus version - details there.

As for the problem, add the names of the pages to an array; generate a random number based on the length of the array and use the go to page function with the select array element.


Code:
//names of pages
myArray = new Array ("pageOne","pageThree","pageNine")

//random number
r = String.random(myArray.length)

//output page name and go to that page
Debug.trace(myArray[r])
GotoPage(myArray[r])
