How to tile a texture?

This is the tutorial I am following and it seems for them, it was automatically set to tiling from the start, but for mine it is clamping and stretching. When I went into the M_Concrete_Tiles and set the TexCoord from .5/.5 to 5/5 it looked better, for the floor texture, but when I tried to increase it for the wall texture M_Concrete_Poured to something like 1 / 25 and 25 / 1 and nothing changes. I am not sure if I’m not changing the right TexCoord’s values for UTiling and VTiling. I’ve seen in other post about this advanced option setting texture to clamp or tiling but I have been unable to find this option. Any idea how I should go about trying to tile the wall texture?
