crystal reports: set up a dummy parameter as null

Question

I am a novice in Crystal Reports and I need help. I need to set up a parameter as a selection for null value. I, for example, created a dummy parameter called, "No name" and am trying to set it up as a null value in the dataset.

Any suggestions, please?
