@@ -28,7 +28,7 @@ There is one function in the `fingertipsR` package that extracts data from the F
 * AreaTypeID (this defaults to 102; County and Unitary Authority)
 * ParentAreaTypeID (this defaults to 6 for an AreaTypeID of 102; Government Office Region)
 
-At least one of *IndicatorID*, *DomainID* or *ProfileID* must be complete. These fields relate to each other as described in the introduction. *AreaCode* needs completing if you are extracting data for a particular area or group of areas only. *AreaTypeID* determines the geography to extract the data for. In this case we want County and Unitary Authority level. *ParentAreaTypeID* requires an area type code that the *AreaTypeID* maps to at a higher level of geography. For example, when combining groups of County and Unitary Authorities it is possible to create Goverenment Office Regions. These mappings can be identified using the `area_types()` funciton. If ignored, a *ParentAreaTypeID* will be chosen automatically.
