I want to show a message like "You must select 1 item in order to process" from a radiobutton list, what would be the code for that.
What is the primary objective of this campaign?
0 Lead generation
0 Image Building
But in order to go to next page, the client has to select atleast one item. If nothing is selected, then I would want to show them a message saying that :You must select at least 1 item in order to go to next question.
Thank you all in advance.
