Touch screen does not respond after glass replacement?

I cracked the glass on my phone. Functionality and everything worked fine. I decided that I was tired of the glass chipping away and went about changing the screen. Everything went well and the new glass was installed. The phone turned on and the screen looks great, but now the touching the screen there is no response. The back and home buttons worked. Voice command works. I removed the new glass and tried a new one with no change. What could this be? Any suggestions or tips would be great!
