Winforms - Print Preview code VB. Need to change my code so that it will only print pages selected

I need to be able to change my print code to also allow the user to select the pages they want to print. I aquired this code from a previous question asked a year or so ago. It works fine execpt for this issue and one other issue that I will make a new Q for. I am including the code I use and also a print screen of what comes up when running the app.
