Clamping x position on after effects

hello,
Is there a way to clamp a X Position opn after effects on several different values?
I've been using this code:

x1=1024.3322
x2=1224.1572
clamp(transform.xPosition,x1,x2)
if (transform.xPosition>x1) {
transform.xPosition=x2;
}

But that only allows me to snap from one position to another. I'd like to be able to snap into 6 positions (on X dimension).
is there a way to do that?
I use the Snaped position to get the position value and use in another layer but i really need to be clamped.
Thanks,

GR

Hey Dan,
I knew you would come for the Help.
Right now for some reason it's not working.
im not sure if i made myself 100% clear.
Check the file i uploaded as an example of what i have now. Just slide the layer to On and OFF.
Download the AEP here:

But instead of ON and OFF i would have Value 1, Value, 2 Value 3, Value 4...
Im adding your code on the xPosition but i get the Layer stuck in one single position.
Thanks again for your help!

Hey Dan,
What if i want to slide a layer on the xPosition, but having a limitation.
Let`s say i want to slide it from 1024 to 1530, not clamping just being able to slide from 1024 to 1530, limiting the beginning and the end to those values?
I`ve found similar possibilities, but none quite the same here on CC.
THanks again in advance,

Yes, i want to do that on the Viewport.
I know about the slider, checkbox and stuff on the Effects tab, but i want to do that on the viewport. you know what i mean?

Actually that's perfect.
I didn't know Clampping would give me that result.
I thought that clamping would be more like snapping.
THanks again man, that helped!
