Hello, I just can't seem to get this to work.

I found these previous:

(Couldn't get this done, it tells to comment }else and there is plenty of them)

and

http://osticket.com/forums/showthread.php?t=2682(http://osticket.com/forums/showthread.php?t=2682)

And it still doesn't work correctly.

If I add somewhere for example 74959742 (8 digits), it will find it.

However if I have for example 1234567 (7 digits) or 843255242 (9 digits)

it doesn't work.

if I add new with 8 digits, like 22447753, it still doesn't work...
