Can you post an example table with multiple entries? Based on what I'm seeing, your data is in a very unfriendly format for JMP. Keep in mind, JMP is not a spreadsheet program like Excel. On the surface, this feels like trying to coerce JMP to be like Excel. If that's how the data comes, we can probably do some pre-processing to get the data in a better format. That's why I'm asking to see a more thorough example.
