Widget doesn't work correct when using WB embed-code

I made a flash widget wich works perfect with my own embed code on my own website and in the widgetbox control panel it also works fine. But if I use the generated embed code from widgetbox it seems that some functoins in my swf fail.

I've got 3 thumbnails which show a larger image when you click on it, but that does not work when I use the widgetbox embed code.

Here you can see the difference between my own embed code, and the one from widgetbox. (They both use the same swf file)

It would be great if someone could help me out!

edit:
Does it have something to do with levels?
