a TEASER 4 U ALL
hi friends, gud morning, well i have a simple query 2 ask u.
look i have a script that displays a question to a user along with 3 answers from which he has to choose one.
once he chooses an answer and clicks on submit button, he gets a message whether it is correct or not. also the next question appears.all this works fine.
but incase the user doesnt choose any answer and clicks the submit button, i awnt that he should get an javascript alert box to popup saying he should choose one answer . And only on choosing an answer should the next question appear.
kindly tell me how this can b done. i am sending the extract of my script.waiting for a solution very badly.plz help

RE: a TEASER 4 U ALL
well it works but not the way i want...i changed onsubmit to onmouseover..
php Code:
Original - php Code 
  1.  
  2.     <form action="result.php" method="post" onsubmit="cheka()" name="form1">
  3. <script language="JavaScript">
  4. function cheka(){
  5. if(!form1.corr.checked){alert('Answer plz');return false;}
  6. }
  7. </script>


now the problem is that even when i select one of the answers and move the mose over the button i get the alert which shouldnt happen
the alert shld pop only when i dont select any answer
