Forums Scripts & Popups troubles with a draw script

First i'd like to thank you for your help, but there are some things i can't place!

Some numbers were draw double, but all the teams and crews have to be draw a single time.

I really hope you can fix this bug..

this is an example of a test-draw. not all the numbers and alphbetical characters have been taken!
