I'm Using a (Gravity) Form to create Custom Posts 'Bedrijfsanalyses'. The Custom Post Type contains custom fields, created with Types. I want to calculate the average from certain custom fields, calculated from ALL Custom Post Types 'Bedrijfsanalyses that contain that certain custom field.
What I have found in the Forum is that this isn't possible with Views without some extra coding. I have to create a function and shortcode to do the job, but I didn't find how to do this. Could You please help me?
