The following control source is used to calculate totals on a Report that has 2 sub reports, and a sub report on a sub report. It works well, thank to this lounge. My problem now involves getting a #Error message when one or more of the sub reports returns no data. Any and all assistance is very much appreciated. TIA.
=rpt_CME_Totals!rpt_Emt_Refresher![total time]+rpt_CME_Totals![sum of hours]+rpt_Run_Review![sum of newtime]
