I'm sorry to hear that you are having trouble viewing a post, @ElletonMccullou. The best person to contact about this is your instructor. Your question was posted to the global Instructure Community. While there are a lot of helpful people here, they are unlikely to be able to answer questions specific to your course. However, it's possible that discussion has a requirement that students post first before they can view their classmates' replies. That's a question your instructor can answer.
I’m going to mark this reply as a solution. I realize it does not solve your problem, but it will be helpful for our colleagues who face a similar challenge. I hope you are able to get access soon.
