What did you put in for the servings? That should tell you. If you put 8 in for the number of servings it makes it is per serving.
BTW it tends to cap the fiber for the whole recipe not per serving. If you can I suggest purchasing a software program to install on your computer called Mastercook. You can get it for $5 plus shipping/handling at
http://www.5dollarsoftware.com/ . You can create your own cookbooks and it does nutritional information, you can add ingredients (great when you use brand name items since all data bases --- including the one at W/W Recipe Builder --- are usually an average of 2-3 different brands), it even has a lot of other functions like grocery lists, planning, etc.
