The HTC One X screen is incompatible. You don't have the One X, as much as at&t want to market it that way it's actually the One XL. So, now that you know that you should know that there are three different screens for our phone, you need to open up your device and take note of the colour of the flex cable attached to the screen. Once you've done that you know which of the three screens you need.
PS. Please search our forum before posting next time, there are many threads already discussing this in detail.
