The Armour and the hearts doesn't show.

[Klein]

I don't know why, but when I am in survival the hearts and the armour icons are default. Some reason to why happens this? In a video I saw this texture pack and had the icons. Please someone help me, thanks

You haven't really provided any useful information for anyone to try and help you.

Exactly how did you install the textures?
What version of Minecraft are you playing?
What version of the pack did you download?
Please provide a screenshot of the resourcepack screen.
