Re-layout does not work??

C

Confused

Why does re-layout not work on an organizational chart.

I am revisiong a chart prepared by somone else and I cnanot get it to work.
Is there a settign that has turned off this feature. The error message says
add shapes and select superior shape.

If i open a new chart this feature works but I do not want to start form
scratch.

Thank you,
