Check the formula starts with an = sign. Then check the cell references are correct — e.g. B2:B7 not B2-B7.
Check your internet connection, then try refreshing the page. If it still won't load, try a different browser.
Check your OneDrive first, then check your Downloads folder. Use the search bar and type part of the file name.
Re-download the .hex file and make sure it lands on the MICROBIT drive, not somewhere else.
Click the chart, then go to Select Data, and check the highlighted range matches the data you actually want.
Press Ctrl+Z to undo — this works in both Excel and Word.
