the only thing i see on the website is a blank area and an "X" in the upper left hand side
Normally this indicates that the file is missing.

the script that xara pro or xwd creates is all i should have to copy in order for it to work
Which script are you talking about Frank?
You say you have created the .swf in XWD ?
I assume then that you have exported the .swf file to your HDD and then embedded the flash into your (other) html?
There is no script at this stage, only a single .swf file (unless you embed the flash into a web designer document, which will then generate the script when you export to html)

In other words, how are you using the flash file which you created in XWD?
