Ah ok, now it's clear.
Well, it should be the "Default" layout you want then.
In the HikaShop backend, go to -> System -> Configuration -> Display tab -> Default parameters for products. There you'll see the mentioned "Layout on product page" parameter. Set it to "default", save, and reload a product page in the frontend.
If it doesn't change to displaying the price to the right of the image, there could be the following reasons:
- For your existing products the same parameter is set to "Reversed" or something else, this overruling the default setting. Go to the product edition page (HikaShop backend -> Products -> Products -> then click on the product's name), look for the parameter in the left pane somewhere below Description, Alias, etc, set it to "Inherit" and save.
- The Joomla template you are using has an override for the "Default" layout. However, for now and as a first step, let's assume that's not the case.

If you'd still have trouble, it'd be better if we could see your site. So, a link would be good then.

Don't worry, maybe it's not necessary. And if it is, it's not THAT difficult, and unless you want or need major changes, chances are good that you get specific instructions here.
