In Harmonic Analysis i'm receving one error message
"Encountered an improper argument".
This error message was comming while selecting the "user select ferquency phase pairs" not for the ceasar II select frequeccy phase pairs". If I provide damping ratio this error message was not comming.

so this error because of damping ratio or because of other condition.
Can any one can explain.
