By providing more details you are helping us to make more exact reply. 

Otherwise I can suggest that your "Save" button is disabled.

Please clarify:

- what is your application under test;

- what steps are you doing to implement your scenario (code or keywords sample);

- what kind of error do you receive;

- better if you can attach a screenshot of problematic area and/or properties of problematic element;

- any other useful information.

Thank you.
