Assigning superelevation to corrdior

It thinks you are still picking superelevation sections.  Notice your prompts at the cursor.  First prompt is "Pick Superelevation section" Next prompt is "Pick next superelevation section - Reset to stop picking".  After Reset, (right click) then it will ask "Pick Corridor"

Thank you for your replay, in doing everything you are saying, but when its time to choose the corridor I can’t pick it

Is the corridor 'outline' visible? By that I mean the construction class element with the tick marks that represents the corridor object? 

The corridor is visible and I can see the dynamic cross section

Two thoughts to offer here Sarah:

1. I have seen occasional odd behavior that I have not been able to find a cause for be remedied by reattaching the corridor. 
2. Does the template being used by the corridor have the superelevation flag set for the points that will use the superelevation?
