Mac Auth Rewrite SSID Issue

Hello All, I have had this setup (http://wiki.freeradius.org/Mac-Auth) for a long time and it has been working well. Now I am experiencing an issue with the rewrite of the called station id to extract the SSID from the wireless. Anyone know how I can update the rewrite called station id function to allow the SSID to have spaces? For example, "called-station-id = 00-11-22-33-44-55:SSID WITH SPACE" is just extracting the SSID as "SSID" I need it to show as "SSID WITH SPACE" but aswell be able to process others like "SSID-NEW-SSID01" Any help is appreciated. I think I am overlooking this, but I could be wrong, so any help would be great. Thanks.
