The code has stopped totallingall the used sessions (events lableled PT Session) in the field "Used Sessions" on account.



Please let me know if you can figure out why. It's working for some accounts but not all. I also need the "system admin" profile to be added on this line"

#6     Profile sysAdminProfile = [SELECT Id FROM Profile WHERE Name='Corporate' LIMIT 1]; 


Thanks for your help!
