TSRef - TypoScript Reference
1.1.2. General information
Case sensitivity:
All names and references in TypoScript are case sensitive! This is very important to notice. That means that:
myObject = HTML
myObject.Value = <BLINK> HTML - code </BLINK>
is not the same as
myObject = html
myObject.value = <BLINK> HTML - code </BLINK>
The latter case will not be recognized as the content-object "HTML". In this manual the case of objects is therefore important
