Random Spawn Location Between X Coordinates

How do I get random spawn location at X - 0 but in between the edges of my layout?

Let's say 1st random spawn is at Y 132

2nd is at Y 386

3rd is at Y 214

Thanks for the any help

random(50,100)

..for example, will return a value between 50 and 100

choose(132,386,214)

will randomly return one of the values listed.
