Texture map (UV) good until rendered?

Hello!

I’m just working with a test box to try to figure out what is wrong with my textures. I’ve just textured each side with a number 1-6 and mapped it as a png file. In 3D view, it shows that it’s mapped correctly, but when I F12, render preview, certain sides are either blank, or show the entire texture file on one side.

Any ideas? Thank you!

In the Material Texture settings did you set the mapping coordinates to UV

Big THANK YOU
