Hi all,
I am not a javascript expert. However I have managed to get the following code working. As you can see there are two radio buttons. None are selected by default. Clicking next without selecting one will bring up the prompt saying "You have not selected an option".
If you select the bottom radio button the text box below is then enabled. However I want to check there is something in this text box when the form is submitted BUT only if the second radio button is selected. I am lost where to start. Please can anyone advise..
