I'm not sure how you're activating your template.
If you have a template tiddler, tagged $:/tags/ViewTemplate, with the
following content:
<$list filter="[all[current]has[content-tiddler]]">
<$transclude tiddler={{!!content-tiddler}}/>
</$list>
Then any tiddler with content-tiddler field will include content from the
tiddler referenced in the content-tiddler field.
The outer list filter is to prevent the template from being activated for
other tiddlers that don't have the content-tiddler field.
Good luck!
