There's no problem really, you just haven't used the variable PV yet for anything other than storing information in it. It's just informing you of that in-case you've created a variable that you're not using for anything which is a waste of space.
If you want to get rid of the warning, then use it somewhere, the code you have is fine. Use it somewhere like in a statement...a function, anywhere.
If you're not going to use it anywhere, why have it
