redirect works but code after doesnt

heya, so i was learning how to redirect code and i've been trying to randomise redirects. essentially, i expected the code to run the redirect and it has, it redirected to the page, but then it will run some code however resulting in an error sych has "it cant find the file, or run the code after it", i assume its because i'm using document.write after the redirect? please help below is my code: https://pastebin.com/8yA91AAs it doesnt run the code after redirecting it, but the redirect works
