Hi Denny,
We'll start with the assumption that you didn't get a defective screen, which is always a possibility; if that turns out to be the case, iFixit has an excellent customer service group and is happy to help, but lets not assume that right away.
From what I've seen, generally those types of problems are caused by not getting the digitizer plugged back in fully to the motherboard. Those connectors can be finicky and sometimes a little tricky to get back in just right. So what you'll have to do is open it back up and follow the guide to where you can unplug the digitizer.

Get out your magnifying glass and a bright light. You're going to want to carefully go over the digitizer's flex cable looking for any signs of tears or damage, then check the connector itself, both on the cable and the motherboard, for any signs of bent or broken pins. Bent pins can sometimes be straightened with some fine tip tweezers.
Assuming it all looks good, clean both sides with 90% or higher isopropyl (rubbing) alcohol. Let it dry for a moment then plug it back together and retest.
If it still doesn't work, you may need to plug in the old screen to verify that the touch screen on that still works; if so, that would point to a problem with the replacement screen.
Give that a try and let us know what you find and we can go from there.
