Hi Connor,

We could fill them in straight for you on the spot. Instead I think it would be more beneficial to you if we simply give you some pointers.

As you can see the code is a simple 2 dimensional array whiich requires 2 loops to iterate over. You need to provide iteration variables (which could be any name of your choice to make up the structure of your for loops and than use them to fill in the array indexes.

To kick off, you could for example use use j for the inner for loop and i for the outer for loop.
