Where and how to display custom fields

I work on a new site for the Peoples University In Denmark - Horsens / Has used wp before-
I need two custom fields, which by convenience are already here and are easy to modify.

My custom fields are "Speaker (In danish: foredragsholder" and "Subtitle" (to the event-title).
However .. I need the "speaker" and "subtitle to be displayed in the main event display, right below the "Title"
See attached

Ps. (Just bough the extension yesterday") / Placed my first (same) topic in wrong category)

Hi Kim

To move the field to that position, you will need to edit code. Do you know programming so that I can guide you ?
