In a Cognos report i have 2 checkbox prompts named :

• ChoicesIndicator1_VALUE
• ChoicesIndicator1_VALUE_b1

When the first one is clicked / unchecked, the second one has to also be unchecked.

I can’t do this with Cognos so i’m using javascript.

The idea is as follows :

<script>   

var form = getFormWarpRequest();
var myList  = form._oLstChoicesIndicator1_VALUE 
var myListb1  = form._oLstChoicesIndicator1_VALUE_b1 

myList.onclick = function() {myFunction()};

function myFunction()
{
          if(myList.checked == true)
          {   
             myList.checked = false;  
          }
}

</script>    

The if is working but not the “myList.checked = false”; (an alert(“hello”); is working).
So i guess there’s something wrong.
Note : i’d rather use the prompt name if possible. If the prompt ID is needed, can it be attached to the prompt with JS code ?

Anybody knows how to correct this ?

Thanks a lot ! I’m a javascript beginner.
