i am having a problem passing a variable in flash to a javascript function that calls lightbox based on the variable passed to it by flash.

the flash code is:

getURL(“javascript:show(” + w + “)”);

the javascript is:

function show(url) {  
var a = document.getElementById(‘dummyanchor’);  
a.setAttribute(‘href’,url);  
myLightbox.start(a);  
}

if i pass it a url, it works fine. when i use the variable i am getting a “invalid flag after regular expression” error.

Any help would be very much appreciated.

Thanks in advance.
