Why can't I include a page from another space with the Include Page Macro?

[McLovin]

I'm working with two spaces and I'm an admin on both. I want to include a page from one space in the other space using the Include Page macro but it won't render.

• The space with the page I want to include is called 'IOP' (this is the space key)
• I want to include a page from IOP on a page in a space called 'PPS' (the space key)
• The page I want to include in the other space is called 'The 7Ps Cycle'
• I've added an Include Page macro to a page in the PPS space and specified the following:
  
  IOP: The 7Ps Cycle

The macro will not render the page and gives this error: "Unable to render {include}. The included page could not be found."

I believe I'm following the Confluence documentation exactly which for this macro says:

"If the page or blog post is located in another space, add the space key and a colon in front of the page name. For example, DOC:My page name. The space key is case sensitive."

Why won't this render?

Thanks!

It turns out it was user error. It works if there are no spaces before or after the colon:

IOP:The 7Ps Cycle <- this works

I did a test in my server instances:

I used the include macro and let the macro grab the page via character recognition. 

The page loaded. 

If I type it in as you did it has to match exactly but there might be some factors imposed by the browser you are using.

Thank you, Carla. I actually figured out that it was user error. See my answer below.
