Adding Individual Error Bars Excel 2013

Hi,

I'm trying to create a bar chart with three series of data, which have different standard errors. When I add the error bars to the chart, they're all the same height, but the correct values. When I try to click the custom button to select the series to change, the dialogue box that should come up asking to choose the series doesn't appear.

Can anyone see where I've gone wrong?
Thanks

Your chart has one series with 3 categories. If you want 3 series you need to switch row/column data.
