Hello guys, i have searched for days a answer for this, but no luck.
So, here is my problem:

I have a custom field called ‘price’ , where i add the price of the item i am talking about on my site.

I would like to create a function to calculate and display the sum of all ‘price’ fields from all my posts.

Can someone help me with this?

Thank you in advance!
