I just copied your network settings from your screenshot, if you just need repeating parallel lines, you don't need all those nodes.
Here's a very editable way that'll free up the input/output of the warp shader, so it works more sensibly.

Either of the X or Z to scalar nodes decides the direction, the transform shader resizes everything, just rescale in either its X or Z field, whichever one you're using.

Maybe you needed all those other nodes for something else? I don't know. Anyway, I'll be building a mountain then...
