Second MySQL query doesn't work

Answer 1

SELECT * FROM nieuws ORDER BY id DESC LIMI 1, 1

should be

SELECT * FROM nieuws ORDER BY id DESC LIMIT 1, 1

Answer 2

You misspelled limit, you're missing the final T

Answer 3

DESC LIMI -> DESC LIMIT, a typo. Listen to the error messages!

            $select2 = mysql_query("SELECT * FROM nieuws ORDER BY id DESC LIMI 1, 1");

Answer 4

That error messages means your sql query failed. You should add some error checking code to display the mysql error when this happens.

if( !$select2 ) {
  echo mysql_error();
}

I wouldn't leave this in production code but it's useful for debugging your code.

Always a good idea to read the manual:
http://www.php.net/manual/en/function.mysql-query.php
http://php.net/manual/en/function.mysql-error.php
