Variable context
Note that you can use the names of subvariables such as Field or Title without explicitly providing a context. If you do this, the Template Building Block assumes that the subvariable belongs to the variable mentioned in the closest container. For example, Field means Component.Chapter.paragraph.Field in the repeating region called Field.paragraph, but it means Component.Chapter.Field in the repeating region called Component.Chapter.
You can always make the context explicit. For example, if you want to display both the title of the Chapter field and the title of the Component itself within a repeating region called Component.Chapter, either of the following will do:
Component @@Component.Title@@ contains chapter @@Title@@
or
Component @@Component.Title@@ contains chapter
@@Component.Chapter.Title@@
