This error message suggests that there is a problem with the query execution, and the function mysql_query() is returning a boolean value instead of a resource. This can happen if there is a syntax error in the query or if there is a problem with the database connection.

To troubleshoot this issue, you can try the following:

1. Check the database connection parameters and make sure they are correct.
2. Verify that the database user has sufficient privileges to execute the query.
3. Check the syntax of the SQL query and make sure it is correct.
4. Add error handling code to the script to catch any exceptions or errors that may occur during the execution.

Once you have identified and fixed the issue, the script should be able to execute correctly and fetch the results from the database.
