Hi All,

The problem is i am using radio element in my JSP page and depending upon the results, the page dynamically displays the no of radio buttons which equals the no of results. Now my requirement is that when a user selects one radio button and clicks on a button, the JS function looks for the radio button which is selected and returns the value of the same accordingly. But the problem is when the result is only '1' the array length is 0. Hence how do i overcome this situation to return the value of that radio as the value of array in this case i.e. document.forms[0].radioBtn.length is always undefined. I need something to check that only one radio button is present and then accordingly pass on the value of that radio button.

Thanks in advance
