no touch on my touch screen

Mein Problem

replaced my screen

Meine Reparatur

First time i did it, i accidentally smashed the screen down on a smalls screw. had to get a new screen.

Take 2: this time it all is working, but the touch part of the "touch" screen is not working. I'm wondering if its the screen or if i did something wrong? Any thoughts?

Mein Rat

watch out for screws that get lost!... it wasn't that bad to do this. But again, i've bot two screens and I've not got it working yet so take that for what its worth.
