using flashvars in conjunction with getURL

Hey, I have a question, that may be easy to answer I don't know lol. I have a pair of download buttons I'm going to disperse on my site... but instead of creating several instances of these buttons for various links, I would rather use flashvars and put the download link in the embed code. However, there is a preview button that loads a preset size popup window. The code looks like this:

Code:

---

onPress = function() {
       
                getURL ("javascript:openNewWindow('http://www.djsting.com/player.html','thewin','height=292,width=416,toolbar=no,scrollbars=yes');");
       
        }

---

that works just fine, however what I'm trying to do is create a flashvar called ssIssue and sub it in where the link is like this:

Code:

---

onPress = function() {
       
                getURL ("javascript:openNewWindow('ssIssue','thewin','height=292,width=416,toolbar=no,scrollbars=yes');");
       
        }

---

but it doesn't recognize it. How can I create a similar javasript controlled popup script like this that works with flashvars?

Please and thanks :)
