MATLAB: Trouble adding error bars to bar graph

bar grapherror barsgroup bars

I am trying to add error bars to bar graph. The figure looks fine if I run it without the error bars as just bar(coh). (see attached) I want to the bars to be groups as shown. I'm wondering if that grouping is messing up the error bars.
Thank you in advance for any help!

bar(x,coh)

hold on
