is this supposed to be a PHP problem or a JavaScript problem? you can’t fix a PHP issue with JavaScript or vice versa.
if it’s a JavaScript problem please post the according HTML code and not the PHP that generates it.

What I am trying to do is when someone clicks on the YES radio button I

The below code works as long as I do NOT UN-COMMENT the NO radio

Any help would be greatly appreciated.

Hi all,
I got the question about the radio button. How do i
detect previous checked radio button after i checked
other's radio button.
While the new radio button checked, it need to prompt out
a confirm message box, if user click on the 'cancel'
button, system will programatically check the previous
radio button instead of the latest radio button that
checked.

Hi All,
I've come across the problem of not being able to re-enable a radio
button with javascript if its initial state has been disabled in the
Page_Load() method of the code behind.
Might i add that it behaves fine in Firefox, but IE is unable to
re-enable the radio button. IE is fine if the radio button starts in an
enabled state.

Hi,
Am using Tkinter. Suppose I have 4 radio buttons (value 1,2,3 & 4) arranged in a single column. I want radio 2 to have a normal state and radio 4 to have a disabled state when radio 1 is selected. And radio 2 - disabled, radio 4 - normal when radio 3 is selected (i.e. vice versa). My main question here is how do i get to know the state(i.e. normal or disabled) of a radio button as a feedback? thanx in advance

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
