Basically, he's trying to use a variable for the link restriction, and it's not working out well for him. He's using the value zero for his variable, for the link restriction, and I thought maybe that was why it wasn't working properly, and told him to use any other values. If that still won't work, I guess he'll have to find out whether the value is actually the value he wanted it to be or not. And if the value is the value that he was trying to get for the link restriction, and it still doesn't work, then I would tell him to check the link restriction to make sure that he's setting it to the value that he wanted to restrict it by.
