Creating SP in mssql gives "conversation" error - sql-server

Question

I am rewriting my database system from MySql to MSSQL. In my current piece of code i get the error:
SQL80001: Incorrect syntax near ';'. Expecting CONVERSATION.
CREATE PROCEDURE [dbo].[addAnime]
#$animeID INT,
#$animeName VARCHAR(100),
#$animeEpisodes INT,
#$animeSeasons INT,
#$animeGenre1 VARCHAR(100),
#$animeGenre2 VARCHAR(100),
#$animeGenre3 VARCHAR(100),
#$animeArtist VARCHAR(100),
#$animeStudio VARCHAR(100),
#$animeReleaseDate VARCHAR(100),
#$animeDescription VARCHAR(8000),
#$animeImageLocation VARCHAR(1000)
AS
BEGIN
IF NOT EXISTS (SELECT * FROM animedatabase.anime WHERE animeName LIKE #$animeName)
INSERT INTO animedatabase.anime(animeID, animeName, episodes, seasons, genre1, genre2, genre3, artist, studio, releaseDate, animeDescription, imageLocation)
VALUES(#$animeID, #$animeName, #$animeEpisodes, #$animeSeasons, #$animeGenre1, #$animeGenre2, #$animeGenre3, #$animeArtist, #$animeStudio, #$animeReleaseDate, #$animeDescription, #$animeImageLocation);
ELSE IF ((SELECT COUNT(*) FROM animedatabase.anime WHERE animeName LIKE #$animeName) = 1)
UPDATE
animedatabase.anime
SET
animeID = #$animeID,
animeName = #$animeName,
episodes = #$animeEpisodes,
seasons = #$animeSeasons,
genre1 = #$animeGenre1,
genre2 = #$animeGenre2,
genre3 = #$animeGenre3,
artist = #$animeArtist,
studio = #$animeStudio,
releaseDate = #$animeReleaseDate,
animeDescription = #$animeDescription,
imageLocation = #$animeImageLocation
WHERE animedatabase.anime.animename LIKE #$animeName;
END
END
END;
I've tried quite a lot of changes in structure and naming, but none solved the problem. I can't seem to find what I'm doing wrong. Any help would be much appreciated.
Thanks in advance.
