Hi Bob,
Thank you for that piece of information, I’m remember that Mac’s and Window’s excel are different for future work.
Unfortunately I can’t follow Jim’s option because I literally don’t have it appear on my screen when I click my bar graph! I don’t know how else to find these ‘error bar’ options, because all the ways that are being demonstrated through tutorials and advice are simply nowhere to be found on my screen!
The first image shows what the top of my excel page looks like when I click on a graph or highlight the table on excel.

The second demonstrates what does pop up and the only access I have to the error bars (I’m unable to customise them this way). Reminder: I don’t get a little plus next to my graph when I click it either!
