CLASSDATASTRUCTURE and PROCLEVEL Security

We created a CLASSDATASTRUCTURE to defice HR regions, then created the attribute "Region" to assign to users. 
Then we used "PROCLEVEL" to define a conditional rule
if(isStructNodeTitleAbove('ClassDataStructure',PROCESS_LEVEL,user.getAttribute('Region')))
   'ALL_ACCESS,'
else
   'NO_ACCESS,'

yet in testing, they are getting full access to all the regions not what is defined in their attribute. 

ANy advise would be greatly appreciated
