Company Control

We have numerous companies in Lawson for our Finance users and we have moved from LAUA security to Lawson security. I haven't been able to figure out how to restrict security classes to certain companies. I was able to restrict access by process levels with this element:

if(user.attributeContains('ProcessLevelControl',PROCESS_LEVEL))
'ALL_ACCESS'
else
'NO_ACCESS'

and entering the process levels in the ProcessLevelControl field in the user's profile

but it doesn't seem to work with CompanyControl with this element:

if(user.attributeContains('CompanyControl',COMPANY))
'ALL_ACCESS'
else
'NO_ACCESS'

Any ideas how this should be set up? Thanks.
