I am attempting to add a multi-line text variable to a page template. I followed an online video and all seemed pretty simple. When I attempt to add the variable, however, I get first get a message that says something like, "This template uses variables. Once you fill them in, the information you supply will become part of the content in your new page." I then click somewhere on the page, expand the expand macro for example, and the variable disappears. Did I miss some configuration step? I am attempting this work in my personal space, so I am a space admin.
