Subscribing to more than 3 lists

[data-lab]

Hello,

I am trying to modify the 'subscribe_multiple.php' allowing it to offer subscription to more than 3 lists, but the script does not allow to subscribe for more that 3 lists at time even all the 4 check boxes are checked.
1. Is there any special code I should change in 'subscribe_multiple.php'?
2. Is this a limitation set in another PHP file?

Just add the HTML code to handle more lists. There is no limitations. It is just question of adding more code.
