Vizalert - Unable to process alert csv, error: 'int' object has no attribute 'encode'

Version 2

    Hi,

     

    I'm in the process of setting up VizAlerts by going through the install guide. I've gotten as far as testing the RegionSalesWeekly, but I keep getting this error (from the error email):

     

    --------------------------------------------------------------------------------------

    The following errors were encountered trying to process your alert:
    General errors:
    Unable to process alert RegionSalesWeekly as csv, error: 'int' object has no attribute 'encode'
    --------------------------------------------------------------------------------------

     

    Email Error When error occurs, email was sent to designated mailbox not to the recipient.

     

    Anyone know how to fix this?

     

    regards,

    Denise
