I'm trying to put toghether a chart that is based on a few queries. Each of the queries gets a date criteria from a form. (it's the same date for all). The results of all of these queries are on another query which the c hart is to be based on.

When I go to run the query I open the form enter the data and the query runs OK but when I go to run the chart report a get a message saying the database engine doesn not recognize the format [forms]![entry form]![start_date].

Any ideas on this?

Thanks in advance
