can't fix error

Arduino: 1.8.5 (Windows 10), Board: “Arduino/Genuino Uno”

arduino-pong:35: error: #error (“Height incorrect, please fix Adafruit_SSD1306.h!”)

#error(“Height incorrect, please fix Adafruit_SSD1306.h!”)

^

exit status 1
#error (“Height incorrect, please fix Adafruit_SSD1306.h!”)

Error code im getting ^

hi everyone so i am making a pong game im following a guide online, and i can seem to fix this part
here’s the code
the text in the red is were my problem is

Please use code tags (</> button on the toolbar) when you post code or warning/error messages. The reason is that the forum software can interpret parts of your code as markup, leading to confusion, wasted time, and a reduced chance for you to get help with your problem. This will also make it easier to read your code and to copy it to the IDE or editor. If your browser doesn’t show the posting toolbar then you can just manually add the code tags:
[code]``[color=blue]// your code is here[/color]``[/code]
Using code tags and other important information is explained in the How to use this forum post. Please read it.

Do this:

  • File > Examples > Adafruit SSD1306 > ssd1306_128x32_i2c
  • Sketch > Show Sketch Folder
  • Navigate up two folder levels to the Adafruit_SSD1306 folder
  • Open the file Adafruit_SSD1306.h in a text editor.
  • Change lines 73-74 from:
//   #define SSD1306_128_64
