Hi

I an trying to get a report with the interval (day) in one column and the the individual incident queues and their respective totals in individual columns. When i try to get the individual queue for each column e.g. incidents.queue_id=36 i get an expression syntax error near '=36' I have tried all sorts but cannot get it right. Can anyone help please?

Thanks

Tim
