Did you make a mistake? Don't panic. What might feel like a tragic mishap to you could be easy for someone with more research experience to fix. So don't panic, and don't throw anything out. Simply take a deep breath and ask your research advisor what can be done. If you need help starting the conversation, use the words: "This is hard for me to say but...." and follow with: "What can I do to fix it?" And keep this in mind: when you watch how someone with more experience troubleshoots, you learn how to solve problems in the process.
