When making string values the characters that always give the most problem are the " and ' (I don't know whether I should put them inside "quotes". My brain just exploded because of the Recursion...). Below is a guide as to the correct implementation of strings and quotes.

• value="single 'quoted' string and double \"quoted\" string", or
• value='single \'quoted\' string and double "quoted" string', or
• value=[[multiple line
  with 'single'
  and "double" quoted strings inside]]

Hopefully this informations helps more than it confuses...
