[Chameleon] java script variables

[Abbott,Arthur]

Allright I'll try that.  In order to do that I have to use:
 
    function GetJavascriptVariables()
    {
        // init vars
        $aReturn = parent::GetJavascriptVariables();
        $aReturn['NewUrl'] = "http://*.*.*.*/images/softball.png";
        
        // return
        return $aReturn;
 
in the widget correct?  I take it that the variable must be declared in the template.html file? and hopefully lastly, how is it used within queryresults?

When I try to use the value in QueryWidget that was supposed to be set in QueryResults, the value does not change. This is wierd since i know its changing in QueryResult. I echoed the value before and after and the value does change.
