An object in an array in an array?

I am having a weird problem where I am gathering data and then moving through an object in an array in another array.

I have put together the relevant sections of code, all help would be really great!

Here’s the info!

The main problem:
Each “item” has it’s own list of “dimensions” which is an array of objects which each have properties.
It is only able to show 1 object here, anything more and it breaks the next dimension list.

If anyone can solve this I’d be so happy!
