[HELP]Photon multiple Prefabs/Characters

Hi! I need help creating a button in my PUN lobby for a character select. If you press the button, it should take you to the scene where you click the character that you play as. And on play, you should be able to play as that selected character. I have included the files to my project. Thanks! Characters are in resources folder. Spiderman is the first character. The Flash is the second character. https://www.dropbox.com/s/ugw1sn4vyj46ut3/ff738a7f16dceff4e6f4508d5dec7c5f.bin?dl=0 If the link doesn't work, please verbally help. Or give suggestions. Thanks!
