The other (Text1 , Text2)I set for them is don't allow null value . - Step 1: I fill in 2 parameter Text1, Text2. - Step 2: Uncheck "Filler1" and input data "abc1" - Step 3: Uncheck "Filler2" and input data "abc2" - Step 4: Click "Back" button on browser . The result is Filler2 is disable but Filler2 is uncheck . Please help me solve this problem Thanks a lot Live

Hi Live, Only if you define any actions on the report, then you can see the "Back to Parent Report" button and be possible from a report back to another. So, could you let me know which button you mentioned is, the "Back to" button of browser, or the "Back to Parent Report" button in report? Did you create any action for this report? I did some tests for your question, but everything works fine. So I think this issue could be caused by your operations. Please take below scenario as an example: I created a report with an "go to report" action in a textbox, and specified the action go to the same report. So that after clicking the action, it still has 4 identical parameters in report, and it looks like that you always in a same report. In child report, I have tried both the "Back to" button on browser and the "Back to Parent Report" button in report, but if the null option of Filler2 was checked, then Filler2 was disabled, otherwise it was enabled. If there is anything unclear, please feel free to ask. Thanks, Albert Ye
