Hi All,

 

I am working on Hyper Study  tutorial HS-1020: Working with a parameterized file model for size variables file in HM-12.

Following each step as mentioned in the tutorials.

1. Define model  (ok)

2. Define design variable  (ok)

3. Specification  (ok)

4. Evaluate  (ok)

5. Define response -- Getting Error.

 

As per the tutorial : facing the error at Step3: 14th point.

While defining response --> Expression --> Expression Builder --> Evaluate expression

I am getting error like  Error  : cannot evaluate expression (  ), ( response 1 (r_1) )

                                                check if all expressions, preference files, sources and other components are valid.

 

Please let us know what would be the error.ASAP

 

Thanks in advance
