Comparing the distance of 2 points from a z-axis of 0?

Basically, I have a curve with points on it. I'm taking the two end points, and I want them to be moved to the exact same location in the z-axis, the 0 mark. The curve isn't equal on the ends, so I can't simply move two points. I've tried comparing the two points and I haven't been able to figure this out.

What do you mean, "The curve isn't equal on the ends,..."? Can you post a picture?

I do not get it as well. But maybe this is guiding you?

That's what I call being meticulous.
I just love your definitions!

Hey Chris, good to see you again. This is part of the same project I'm working on from before.

In the attached image, if you look where the yellow points are on the ends of the curve, they're at different heights. Basically, when I move them (however I decide to do it exactly), I want them to end up at the same height. I don't want it to be restricted to the curve though. The next time I create a curve, I may have the right side higher than the left.

so basically, I need a way for each side to compare the distance from the 0.0 mark in the z-axis, and adjust themselves accordingly. I hope this makes sense.

Dedackelzucht, I'm not sure if that's what I'm looking for or not. Thank you for your help. I have to leave in an hour, but I'll check it out tonight.

I'm new to Grasshopper, so I'll probably be asking more questions if I keep making things in it.

Oh, I forgot to add, the group I created is all from the parametric bed from before. The portion above is what I'm trying to figure out to further extend on the bed.

i understand this

for exmple, I evaluate ere which has a higher value in z, and the one with the lowest value is aligned with the other

Yeah, that's exactly what I was trying to do, Felipe. I didn't realize it would take so much to do something like this. It's hard knowing what to do when I don't understand all of the options available. I really appreciate the help, guys.
