I am out of town until next Tuesday, but I'll take a look at the link you sent me and see if I think it will work. I know you don't work on this anymore and I don't blame you, but I thought I would reach out because you are the only person I could find online that has posted any relevant solutions to similar issues. I think my biggest trouble is that in squarespace I don't know where the code needs to be posted. I had done a ton of work early on to design an entire website via HTML and then had trouble making it mobile responsive, which made me turn to squarespace, but now I'm stuck because I can't seem to find any help on modifying their templates.
If I made the page I'm working on public and sent you the link, would you mind taking a look at it and telling me what you think?
Thanks a lot for your time and looking forward to hearing from you.
