Hello All-

I scheduled the following schedulable class and I am getting a strange error...

|EXCEPTION_THROWN|[18]|System.StringException: Support for specifying both a day-of-week AND a day-of-month parameter is not implemented.

Code:

global class ICG_FixDuplicateLeadsProcessorExtends implements Schedulable{
    
    // global method - execute
    // Call Batch method
    global void execute(SchedulableContext sc) {
        //  Instantiate class
         ICG_FixDuplicateLeadsProcessor FixDuplicateLeadsProcessor = new  ICG_FixDuplicateLeadsProcessor();
        String seconds = '0'; //Execute at Zero Seconds
        String minutes = '30'; //Execute at every 30th minute of hour
        String hours = '*'; // Execute Every Hour
        String dayOfMonth = String.valueOf(Datetime.now().day()); // Execute on current Day of the current Month
        String month = String.valueOf(Datetime.now().month()); //Execute current Month
        String dayOfWeek = '';
        if(Datetime.now().day()>7)
            dayOfWeek = String.valueOf((Datetime.now().day()/7));
        else
            dayOfWeek = String.valueOf(Datetime.now().day());
        String year = String.valueOf(Datetime.now().year()); //Execute only for year 2011

    //Seconds Minutes Hours Day_of_month Month Day_of_week optional_year
        String sch = seconds + ' ' + minutes + ' ' + hours + ' ' + dayOfMonth + ' ' + month + ' ' +dayOfWeek+ ' ' + year;
    //String sch = '0 30 * 5 5 ? 2011';
system.debug('Scheduled time string---->>>>>'+sch);
system.schedule('Fix Duplicate Leads', sch, FixDuplicateLeadsProcessor);
        //database.executebatch(FixDuplicateLeadsProcessor,200);
    }
    
}

If I remove the "dayofWeek" from the string sch i get the following error...

EXCEPTION_THROWN|[18]|System.StringException: Day-of-Week values must be between 1 and 7

Any thoughts?

Thanks
