I have a form which has 2 x Radio buttons (Yes / No) These need to be filled out. I don't want the customer to carry on without selecting an option.
Is there some Java Script I can add, please?
This is a bad idea. "Locking" the user into a field will cause nothing but irritation. If you want to "force" them to make a selection you can define the field as required and then the file won't be submitted until the field is filled-in.
Many thanks for replying...
Hello again. I've defined the field as Required. But I can save the Acrobat Reader PDF and email it. So the file can be submitted even if this field isn't filled in.
If you add a button with the "Submit a Form" command that should not be the case.
The user will always be able to manually attach the form to an email and send it to you, of course.
