I posted this question a couple of days ago but it there seems to be an issue
with the MS notification system and I can't access the answer that someone
posted for me.

I want to allocate individual values for error bars in a bar chart, I'm
using Excel 2007. There is a customise option but the values you select apply
to all bars on the chart. As the bars in my charts are a mean value in
themselves, I want to show the error applicable to that bar.
