Thank you Kyle! I appreciate it more than you know. My project is due shortly. I sent the details you requested.

Kasi, We'd be happy to glance at what could be going wrong. Go ahead and fill out the form I linked to previously, and I can make sure this is something that is looked at. Thanks Kyle

I would love to, but I do not have that option as I do not have the plan that includes technical support. My plan only includes being able to ask the community for technical support issues, otherwise I would have gone straight to them.

I'd recommend contacting Technical Support about the issue, they should be able to investigate the particular notebook and help identify what could have gone wrong without you needing to share all your information on a public forum: https://www.wolfram.com/support/contact/email/?topic=Technical In your request, please include your email you use to access the cloud, the exact name of the object that won't open, and the objects UUID (available in the notebook's "Details" section from the file explorer interface).

Open my nb file in Mathematica Cloud?
