Using a variable within a page content variable

So, I’m wanting to pull page content into a collection page, based on the collection title.
I will set up the various pages.

In the code below:

{{ pages.collection.title-buying-guide.content }}

If I replace collection-title with the actual collection title, the content is being displayed.
So, I know that works.

However, I need it to pickup content based on the collection title.
But, this code doesn’t work.

Help please :slightly_smiling_face:
