remove prices from certain category listings

Hi all. Read through what I could find and don't think the responses fit my needs.
First, I'm a hypernewb when it comes to hika & php coding - so bare with me.

Ideally, I would like to have some some snippet that would do something like...
... when variants occur on a product, hide price shown in category listing.

But again, hypernewb - so I don't know if this even possible.

I'm currently setting up a store in which some categories will have items with variants, and others will not.
[ Category A ]: Original Paintings (no variants)
[ Category B ]: Prints and Posters (variants)

I would like to list products in Category A with prices.
I would like to list products in Category B without prices until the product has been selected. Then I have different prices for different variations.

Currently I have different descripts/prices for a product in Category B and it works great when changing between the variants.

HikaShop Info: HikaShop Business ver 2.0.0

Thanks for any help. And sorry if I'm missing any important needed info.

The code snippet worked. Too well.
Took and hid EVERYTHING if I put it at the top.
I tried putting it in the Price section and that worked. But it still hid everything below.
So I then moved the entire Price section to the bottom

<!-- PRODUCT PRICE -->
<?php if(!empty($this->row->has_options)) return true; ?>



<?php
}
if($this->params->get('show_price','-1')=='-1'){
  $config =& hikashop_config();
  $this->params->set('show_price',$config->get('show_price'));
}
if($this->params->get('show_price')){
  $this->setLayout('listing_price');
  echo $this->loadTemplate();
}

?>
<!-- EO PRODUCT PRICE -->

<?php if(!empty($this->row->extraData->bottom)) { echo implode("\r\n",$this->row->extraData->bottom); } ?>

Scratch the last post. (I know I could edit it but it did work)
It worked fine but I got to wondering.
I wondered why I was supposed to put this code in the

beginning of the 'listing_img_title' file of the view "product" via the menu Display->Views.

<?php if(!empty($this->row->has_options)) return true; ?>
