Discount on products doesn't show up

[Gamemunchies]

Hi,

 

I was wondering how to get your product in the 'discount' block, or 'sale' block.

 

It keeps saying I don't have any items in sale. 

 

I already tried changed the price on my products but that didn't help. 

 

Where do i need to put my sale-product? So it shows on the website?

 

Plus, I did mark the item as a sale-item but I get this weird empty image (see screenshot Knipsel2). Plus it doesn't show in the blockmodule.

 

How can I get it into the box? (see screenshot Knipsel)
