Thanks so much for taking a look at this!
I downloaded and tried to open your example, but it wouldn’t open. Instead got this message: Document Version Incompatibility - The document you are trying to open was created with a newer version of Hype and cannot be displayed.
Are you using Hype 4?
My current version is 3.6.7.
Would you possibly be able to send me a version that I can open with Hype 3?
