Hello all!

I was hoping someone could shed some light on what I may be doing wrong... I've struggled with this all night and have exhausted my searching options.

What I am trying to achieve is to open a file chooser when the user clicks the Open File button (which is a controlP5 button) and select an MP3 which then converts the path of the file chosen and stores that in a string which then can be played by pressing the Play button.

If I click Open File, it opens the file chooser but when I acknowledge the file, the sketch hangs.

Am I going about this the right way or is there a much simpler way?

Thank you kindly in advance!!!
