var chart1 = new FusionCharts(""

My question is why do you have to use relative addressing with the function call? 

Steps taken:
- created virtual directory under main root web called Fusion charts.  Beneath that folder I placed a folder called SWFile.

Attempted to create web reference.

I've tried creating dynamically:

http://<web root name>/FusionCharts/SWFile/<chart swf file>.swf

That did not work.

I then tried creating an application wide variable for the root web server map path and adding Fusion Charts\SWfile\

i.e.:

c:\<root web directory>\FusionCharts\SWFile\<swfile>.swf

And that did not work.  Are their any hints or workarounds to using  relative address "../../FusionCharts"
