Got some valuable lessons here regarding groups. Beyond but including the issue in this thread, I broke the Detail section of the report into multiple groups. There are a variety of controls in each group, including labels, text boxes and sub-report containers. Each group has the controls inserted into its Header section except the last which has its controls in the Footer section. The app includes a user interface to user settings where the user can stipulate with a check-box the inclusion or exclusion of the last group described herein. The OnActivate event of the report interrogates that setting and sets the visibility of the last section's visibility accordingly.
As discussed earlier in this thread, I did not but it would be a simple matter to table all the calculated values and bind the otherwise unbound text boxes to those fields.
My thanks to HiTechCoach for sharing "The Trick".
