Hi ranchers,

Below code attempts to validate the Gender radio button.
The error is that the objGender.length is undifined. Could you give me some help? Thanks.

"id" name must be unique one in whole HTML page. You just repeated 'txtGender' twice. Correct it.

After you fix your id problem, you can save yourself lot of code by using jQuery on your pages for things like this.

To check that one of the radio buttons is checked, the code would simply be:

I removed the ID, and correct to . And then the code can work as I expect.
Thanks.
