Hi Leo,

In general, we recommend that developers include references to required JavaScript files via the .view.xml file. If you haven't already tried it, you can likely include a reference to jQuery there as well, which might solve your problem.

If that doesn't work, though, you may be able to use the special <%=contextPath%> substitution in your .html file:

https://www.labkey.org/wiki/home/Documentation/page.view?name=addHTMLandWebPart

I don't know what your exact file layout looks like, but it would likely be something like:

<script type='text/javascript' src='<%=contextPath%>/OpenCyto/FancyBox/source/jquery.fancybox.pack.js'></script>

That should work regardless of what LabKey folder/project it's being used in.

Thanks,
Josh
