adding a global turn restriction from a feature class attribute.

I've set up a network dataset in 9.2, but I'm having difficulty defining turning restrictions based on field values in the roads attribute table.  In the attribute table for the roads there are 4 fields which describe if a left turn or right turn is restricted in the from-to direction and to-from direction based on digitized direction.  How can I create a restriction attribute in the network dataset that evaluates the turn as restricted or not??  I thought you could use the turn.angle in an expression but the fields that contain the restriction are not listed?  I've read the online help page and do not want to create a turn feature class because the values are already stored in the road centreline feature class. 

thanks for your help,
