so, yeah.. I Don't Get it.. here is the error I continue to get. Though this works for others it dosnt work for me.. Yes, I'm cursed.Arduino: 1.8.7 (Windows Store 1.8.15.0) (Windows 10), Board: "Arduino/Genuino Uno"

It looks like you took the shotgun approach to library installation. Likely this has resulted in a different LiquidCrystal_I2C library being used than the one your code was written for. There are two options to solve the problem:

  • Change your code to work with the library you're using.
  • Delete the unwanted libraries so that the wanted library is used.

So I guess the shotgun approach isn't the best approach. I deleted all I2C LCD libraries and the sketch compiled! Thank you very much!
