multiple string array to 2d array?

igotabuginmyeye (12)
I've created this array of strings, and was wondering if i could convert this completely into a 2d array whilst maintain functionality of the value swapping?

I've also noticed that when entering some values it seems to output some extra array layers on top of the previous ones. Why is this?

Also is there a way of checking the values against a range to make sure its valid? Entering a value for column or row that isnt in the range leads to some dizzying results!

use a debugger and set some breakpoints
