I have a form, frmChartReports, with 2 unbound controls: StartDate and EndDate. frmChartReports also has 5 command buttons that run its own report which is a chart. Each of the chart reports are based on parameter queries, which use the unbound StartDate and EndDate on frmChartReports. When dates are entered in frmChartReports and each of the buttons is selected, each graph report previews as planned. Sometimes, when the EndDate is changed, and a button is then clicked, the parameter is the same date parameter that was entered before. Sometimes, when the EndDate is changed, the chart parameter is fine. Any suggestions?
