Thank you for the guidance, but the terms of this strange report are a different test I found. The function of this report is that it takes two inputs by the user form. The first value is the number of the invoice number that searches in the query and displays in the main report table, and the second value is in the string, which is attached to a two-option component of the form. This sends the component either the value of "sub1" or "sub2" and the section when print expression set to any sub report. However, the original report runs simultaneously with either its subreport or the second, but in any case, with no data clause added, and in the section when no data type, go to the no data section option if the bets are not executed. Band no data And the white page comes out. A funny point is that even if we delete both subreport and only the main report table, if the condition is still not true and the invoice number is not found, the data no part is executed. In the event that this report is performed, it is not possible for you to make solutions, because the structure of the report is not applicable for the purpose for which this report is not applicable. I will post the report files to attach yourself to the report and see the main problem. Thank you very much for your attention and guidance Report file link: My Report
