I am having trouble creating horizontal error bars in Excel 2007 - there
appears to be no option concerning them. It may be because I am using Excel
2003 compatibility mode - to allow exchange of workbooks with my co-workers.

If it's a Line Chart type you are using, try changing to a XY (Scatter)
Chart type instead.
