Just do something else. I can only rack my brain on the same problem for so long before it's pointless. As one of my professors often says "I've solved more coding problems in the shower than I ever have in front of a computer.

I have to do this a lot. Sometimes I really just want this one issue to get fixed so I can move forward...and when I'm literally out of ideas I just go clean or something to come up with more possible reasons it isn't working...almost there right now lol
