Search a multiple dimensional array

So I'm really stuck on this one. So I have a multi dimentional array of numbers and they are random I need to be able to search for a given number where ever it is. It could be in any row or column. I know I need to use an array formula but can't quite get it to work.

In this example I am trying to get index() to reference 200.

In the end I will also need to return all the values below the 200 but that is easy if I crack the referencing as you can just add +1 to the row.

I've managed to get it working if I know which column the value will be in but it could be in any column or row which is when the problem comes in.
