Sure thing, thanks for helping 

Error is "Condition expression must be of type boolean"

What I'm trying to do is write a scheduled class to iterate through our Account Team member records each night and populate custom fields I've set up on the account record itself to show the values.   This is because reporting on Oppotunities for instance and including Account Team membership is difficult.  So since I can't trigger the update to the Account Custom fields from the Account Team Member object I'm trying a solution with schedulable batch apex.  Here's the (unfinished ) code I have so far: 
 

global class UpdateAccountTeamFields implements Schedulable {
    
    global void execute (SchedulableContext ctx){
        Map< id, string> BackupCRDmap            = New Map <id, String>();
        List<Account> backupAccts2Update    = New List <Account>();
        Map< id, string> CollegeCoachCRDMap = New Map <id, String>();
        Map< id, string> BackupNCRDMap      = New Map <id, String>();
        Map< id, string> CenterCRDMap       = New Map <id, String>();
        Map< id, string> EdAssistCRD        = New Map <id, String>();
        Map< id, string> UKCRDMap           = New Map <id, String>();
        Map< id, string> TransitionCRDmap   = New Map <id, String>();
        Map< id, string> CSDMap             = New Map <id, String>();
        Map< id, string> EdassistCSDMap     = New Map <id, String>();    
        
        List <AccountTeamMember> ATM = [SELECT id,  AccountId, User.Name, TeamMemberRole,
                                                    Account.CRD_Back_up_gsrule__c,
                                            		Account.CRD_Center_gsrule__c,
