Messed up Website

Hello,
I was trying to add more code to play with “excerpt” in function.php, but the code change nothing, so I remove it, and after I pressed Update File – The website show Server Error 500, so I assume I delete somehow by mistake maybe row or two, and I am not sure how can I get it back.

Here is the code
