Worldcup database: queries.sh 1.1:11

Hi, this last task is not getting through.

You should correctly complete the queries in the queries.sh file. Fill in each empty echo command to get the output of what is suggested with the command above it. Only use a single line like the first query. The output should match what is in the expected_output.txt file

although there is no difference after running the diff command with the expected_output.txt?
how to handle this?
