Thread:Project:Support desk/parserfunctions help

Is there a beginner's version of Help:Extension:ParserFunctions? I found a template on a talk page I could adapt to mostly do what I wanted but when a field is empty it leaves a line blank (see here for an example), on the right under "external articles by viewpoint", all that whitespace is unused template calls) and it takes up space. Thanks, [[User:Modrobene|Modrobene]
