Lost related products - where'd it go?

Hi.

I had the related products working fine. I was manipulating the layout for the price in one of the "default_view"'s.
I just now realized that the related products doesn't show up anywhere.
I may have messed up something in the hikashop / display / content module

So questions abound....
1. Is there a file .php or otherwise to see where the "related_product" is called to see if I might have deleted it accidentally (using laptop and touchpad does wonky things)?
2. Is there a radio button I would have clicked to shut it off?
3. Would have messing with one of the "Associated products listing for category listing menu" caused it?

Thanks

I've come to the realization that what I thought was the "related products" was actually a module for showing items in the same category.
I'm a newb when it comes to Hika, so sorry for my ignorance.

I'm now in need of someone to give me a walkthrough on how to get the related products concept to work.
I've selected the necessary items "related products" but now need to get them to show up.
Do I need to setup a module or something for it to work?
Please help and remember I'm a newb so be gentle.

Thanks!

Yep. That worked perfectly. Related products working.

Where would I find the code to change how many columns show on the related products? products: related.php ?
And...... what would that modification be?


EDIT: found it right after I posted this.
modification option in newly made Related Module.
worked fine.
