Checkbox list

Thanks.
Another issue I am facing is In work flow. I have check box which is going correctly. But For eg:
a) If JOB.DECISION=YES then I have one flow and b) If JOB.DECISION=YES && JOB.STATUS=YES then need to Close. But always even if b(JOB.DECISION=YES && JOB.STATUS=YES ) is satisfied still the flow is going to a. Always it is rotating in a with out going to close. Kindly advice
