Hey Sean,

I think I may be confused by your question so can you answer the following-

When you say "judge" do you mean that you want the step to determine if the result lies within the limits defined by the user?  Is the result numeric?  String? Boolean?  How is the user inputting the limits?

Most of the time people use the Numeric Limit Test step to determine limits on measurements.  This determination is accomplished by the Status Expression of the step combined with the limits set for that step.  How that is setup defines whether the step passes or fails.  If you let me know how the user is inputting the limits I can help you dynamically set the limits.  Which is most likely what you'll have to do.

thanks,I have solved it.in fact ,I just need to change the step as a numeric testing not a action,then the limit can be setted .
