I'm stumped

[jenandbrent]

I came across this puzzle today and just couldn't get it going. Can someone tell me what I'm missing? Thanks!

In the '2 2 2' column the marked square can only be part of the middle '2'. So there's another '2' above and below it.

Thank you! Don't know how I missed that.
