I have a query that is setup with the group by total, and many of the fields set to SUM. I have been using these sum totals to generate charts in both forms and on reports. One chart is supposed to show 2 styles of rental equipment vs the number of clients. In order for this chart to work, i need a field on my query that would contain the # of nonrentals. I enter an expr. in an extra column on the query... and when it runs, the parameter entry windows pop up... 1 window for each field mentioned within the expression. If i just hit enter, the query runs perfectly and the expr. returns the correct value.... but I dont want the prompts to display. I just want the query to run, the expression to calculate the value, and the results to show.
