After full screen replacement, screen registers only half of touches

The lcd and digitizer was cracked so I bought a full replacement for it and installed. The screen looks great, just like the original. I bought the grade S replacement off of etradesupply.com. After playing around with it for awhile I've worked out that it still recognizes touch in all of the areas of the screen but if i sit there and tap the same areas multiple times it will only register half of the presses. This of course makes texting atrocious. Does anyone have any idea why this would be? Please and thank you for you help.
