Business process error in production

Hi,

Business process successfully running  in Dev environment.

But giving the error in Production environment.

Error message:

"An error occurred while applying the value of the parameter "GlbPopupWindowText" of the business process element:

    Unable to compute expression "[#[IsOwnerSchema:false].[IsSchema:false].[Parameter:{35efc48b-729e-4060-93e1-c263b244e32c}]#]", error: Formula value error: Expression expected (at index 0)."

but in business process there is no expression like above.

Any help on this.

Thanks
