Story Points Burndown for specific status

Hi ,
I am trying the same but in my case, story should go through one more status called Development Started before the final status (which is LCO Backlog).

Could you please suggest where I should put this condition.
I tried this but didn’t work:

sum(
  Filter(Descendants([Issue].CurrentMember,[Issue].[Issue]),
   [Measures].[Transitions to status] >0 AND [Measures].[Transitions from status] matches 'Development Started'
  ),
  ([Measures].[Story Points history],
   [Time].CurrentHierarchy.DefaultMember,
   [Transition Status].DefaultMember)
)

Regards,
Neetu
