Enter Parameter Value

To fix this you must create a second query based upon the first query. Delete the calculated expression "Sum of Workload/Sum of Numbers of OM" in the first query.

Put this calculation expression in the second query. Run the second query and you should be ok as it will draw the data directly from the first query. You do not need to run the first query as it will be prompted by the second query.

This (parameter request) occurs because you have a calculation of aggregated fields and Access doesn't like this.

Hope this helps you out.
