Custom error bars not showing

Hi,

I am having a issue with custom error bars. I am use to using this function in excel and have followed the usual route. However, on this occasion when I attempt to add my custom standard error values to the chart nothing happens, no error bars are added. All the pre-set error bars such as % and SD seem to work fine, there is only this problem when I attempt to add my custom error bars.

The plot however thickens further, on some of the charts I can add three out of the four custom values, as you will see if you attempt this however the fourth value does not appear. On the first chart I get nothing each time I attempt to add my error bars.

I have tried several different things out and still nothing works. The error bar values are below the charts, the black line requires the top values reading left to right and the gray line requires the bottom set of values.

Any help here would be amazing as I have a few of these data sets and they all seem to have the same problem. I use 2007 version.

Many Thanks,

Tom
