Topic: "Gallery Not Found" message displayed when I previ

I'm a novice to web building, so please bear with me.  I'm using Dreamweaver 8, a Mac, and SimpleViewer Pro.  I've followed the instructions & was able to get my images & thumbs to work properly by clicking on the  viewer.swf  file. Everything looks great.  But, after I insert the  viewer.swf  in a layer on my web page ( Insert > Media> Flash) & then try to preview on my web broswer, I get the message "Gallery Not Found".  I seem to have everything I need in the correct folder.

Am I inserting the correct file (viewer.swf) into my layer.  Should I be linking it?

I would appreciate any suggestions!
