Is the CA Form 540 "What if worksheet" a calculating form?

I did a planner in 1040, when in the CA  planner, no federal #s transferred, so I input the CA figures, but the system still does not calculate tax liabilities.

There is a box on top of the "what if" form that says check this box to turn off Federal transfer of values. I made sure this box is unchecked.

Please help.

Thank you.
