It seems to suggest that there should be another return statement. Is there a problem in adding it?

Thank you, I just had to look closer at the return statement issue, I had to change the method to void to fix the problem. Got me thinking thank you.

Actually, not quite. You just forgot to return for all cases of the conditional. The first case, if true, caused the entire method to lack a return value. Take a third look!
