Spry Radio Group Valid Message - Is not working properly

[jnutella]

I inserted a radio group, the radioRequiredMsg was created and works fine

but no radioValidMsg was not created.

I created one code i used
<span class="radioValidMsg"> OK </span>
it shows up all time initially or weather valid or invalid stays all the time

not sure if that's the proper coding for it or is it something I am doing something wrong

I found one example and use it code
<img src="../../images/ok.gif" title="Valid" alt="Valid" class="validMsg" />

same thing happens the message shows up all the time and stays there no matter what

Any Suggestion

Thanks
