Burndown chart and remaining story points

[NICK ORR]

I have a remaining story field that I want to use on my burn down chart. I have selected remaining story points as my estimation statistic. 

I get a drop down lists of fields available for me to select in the burn down chart and I can see the remaining estimate field. But it doesn't let me select it. I can select some of the other fields e.g. completion% or aib cost. 

Confused why remaining story points is in the drop down list but I can't select it. 

Any thoughts

Could you describe "can't select it" in more detail?  What happens when you click?

[NICK ORR]

Nothing happens. I click on "remaining story points" in the dropdown and the current selection remains.

Other field can be selected but a number of them including remaining story points cannot

Hmm, I can't replicate this.  Are you on server or cloud?
