Adding product variant metafield to product page

[Daniel_Ward_CC]

Hey all, 

I'm trying to add a variant product metafield to this page, below the price but above the Quantity. 
https://slowageing.co.uk/products/essential-bath-shower-essence?variant=40509019652279

I've tried adding this code to the right area, but it's not calling up the variant metafield, can anybody help me get it working? 

<p> Size: {{variant.metafields.my_fields.size}} </p>

Thanks! 

Dan

Update, I have managed to make the variant metafield display correctly with the following code:

            
<div><p><strong> {{ current_variant.metafields.my_fields.size }} </strong></p></div>
            

However, if the metafield is empty (which it will be for some products) a "0" is being displayed on the product page. Can anyone help me to stop the "0" from being displayed?

I found a solution in an article written by Alan Ryan here: https://alanryan.dev/tips/product-variant-metafields/. It works great!
