Shape optimisation error

I am doing the shape optimisation and I am getting the responce error.

H:/New folder (2)/Opti/sh2.fem
   'DSYSID  1       Shapeopt'

  *** ERROR # 1000 *** in the input data:
  Incorrect data in field # 4.

I have given the responce from... responses>response name> response type = static stress> Prop(select components,inlet,outlet,wall)> create.

But its not working.
