OK - I can understand that. Interesting part is that if I have Dropbox running on my machine and am using my local browser instead of Shapespark, the page works fine. So, bottom line is that currently, I do not have any way to develop, test, and implement what I was trying to accomplish. I will have to find some way to host the html file.
Primarily, what I am trying to develop is a list of equipment that I use as a menu. When the viewer clicks on an equipment name I would then populate an iFrame with a 3D image and description of the equipment. KInd of a “showcase”. I will have to come up with a different way to accomplish it.
Thanks for the reply and any suggestions you have are greatly welcomed.
