How can i set the default value of a radio buttons group.I see there is a defaul

Select the "Choose process data" option under "Choices" instead of "Enter values below"

I want to preselect one of the radiobutton based on a process value so that when screen appear one of the radio button is selected by default.

Hello, to do that you use the "Default Value" section to populate the process variable you wish to be the default value. This process variable should correspond to one of the values listed in the "Values" section.
