Hello Debby, welcome on these forums 🙂
Sorry to hear you are having trouble getting things to work on your site. Looking at your code, I might be able to give some useful tips to help you along but if it’s not enough, could you send us a link to your site to see it live? You can post it on this thread of use the contact form (with mention of this thread).
What I notice about your code is twofold and all about this snippet:
First, the class needs to be
fancybox-inline but it might be just a type-O…
Then, the script needs a href attribute but your code uses
xlink:href which is likely not recognized by the script. Could you either change that to a simple
href or (if xlink:href is needed for another script) add a dedicated href attribute?
