slightly cracked screen now it doesn't respond

I dropped my phone face first on the ground & now there is a small hairline crack in the middle of my screen. Weirdly now, my touch indicator no longer works. it's not responding to my touch. but it still does everything else & it won't shut up! will somebody send me the link to a CHEAP screen I can replace mine with? my email is: shyandchris95@gmail.com
