Question Shader Graph for toon shading not working once plugged in

I'm sorry if this was raised or solved elsewhere, I've tried searching for a solution for days, and have not found anything that can resolve my problem.

I am using Unity 2022.2.20, with the built in renderer pipeline. I am in linear color space (because it was one of the fixes recommended).

In my shader graph, I connect a light direction node (negated), together with a normal vector node, to a dot product node. Then, I change the value range to 0 - 1, followed by multiplying by 5, connecting a floor node, then multiplying again by a range of 0 - 1. In each of these steps, I can see in the node 3d previews that what I am trying to achieve is correct. However, the moment I plug that all in to the base color, the main preview, as well as any materials I use the shader graph on, only displays on shade of color. I can turn the color lighter or darker depending on the value of my last multiplier node, but it does not show the gradient. can anyone figure out why? I have attached a picture of my shader graph:



Any help will be greatly appreciated, thanks

 

Sorry I forgot to mention, I'm trying to create a toon shading shader graph, so the stepped gradient is correct up until I plug it in to the base color, where it becomes a single shade.
