Hi Stan,
Thank for your help. I will check it later. And, do you have any idea how to change number in one position without affected the same number in other position ? Let say I have choose 632 tickets in my package and example of the ticket is : eg : 5-12-18-23-31-45 ,, 5-18-23-35-41-47 and so on. And want to swap( change ) number 18 ( red ) in position 2 with the 20 ( to be 5-20-23-35-41-47 ) to all 632 tickets without affected number 18 ( blue ) in position 3. I try to use swap but it affected all number 18 in the package changed to 20. Is that the only way to do is change it manually one by one ticket in package. How can be to finish all 632 tickets ?
Thank you.
