I have a report that will display the cost for 12 different tasks from 1 to 12. If no cost exists for a task, then it's not displayed at all in the report. For each task, a total cost for each Task is seperately listed in a textbox. Is there a way to sum all these totals from the one textbox they are displayed in? I tried doing sum([Text203]), but I get an error saying Text 203 is an invalid field.
