Use a variable to retain the selected level
If you select a level in the combo box and then open another report, your selection is lost. When you return to the report, it displays the value currently specified in Design Mode. To retain the selected level, hold the selection in a variable and use it as the input and output variable of the combo box.
- Create a report variable called Level.
- Open the properties of the combo box and select Level as the input variable and as the output variable.
