Routing Q.

[eluser]RobertB.[/eluser]
Hello to all,
I'm having problem with the routing system.

This works flawless if I used the table id(numbers).

Code:

$route['(:num)'] = "listings/subcats/$1";
$route['category/(:num)'] = "listings/states/$1";

But if I try to use a permalink field that I have on the table and change the routing to this only the first one works the second one does not take me to listings/states/ but instead takes me to listings/subcats/ again and obviously it give me the Message: Invalid argument supplied for foreach().

Code:

$route['(:any)'] = "listings/subcats/$1";
$route['category/(:any)'] = "listings/states/$1";

Can anyone explain this?

Thanks
