On line #4 you are opening a new PHP block even though the old one hasn’t been closed yet.
You’ll want to delete the preceding <?php on that line. You don’t need it.
Additionally:
You have an extra endwhile; in your else block. The while loop is started and closed within the if ( is_home() ) { block.
The code starting with } else if (is_page() ) { is not in a PHP block. You should either open a <?php block or not close the preceding one.
solved I am having trouble figuring out what is wrong with this code [closed]
