BAII Plus everything, problems, question

Guys dumb question, but I am having trouble with my inputs for TVM problems etc. Example, if i enter N=3 for the periods and then i hit ENTER, then I go to PV to put in 100 but it is already set on 3 from before. then if i change the PV to 100 it changes everything else. Any thoughts as to why I am not locking in my inputs?

Thanks
