Grove pi Scratch LCD display does not display text

When I did the code in scratch for robots(when flag clicked broadcast join LCD join txt hello world) it gave me an error in the scratch controller window and nothing appeared on the LCD display. The error was <type ‘exceptions.IOError’>

It would be great if someone could help. I also tried unplugging every other sensor and it still did not work. Thanks, Jaden
