Let's go through this a few lines at a time. Now we set the values of seven variables. We need to set all seven, so that the code that will execute in the next section will have all the information it needs to format your headline output. The first four variable control the colors of the display. This can be useful for categories, like Business, to the left, that include stories from many different countries.
Legal values are true and false .
If a string were specified, that string would be displayed instead. And that's the end of the variables section. The next section is the actual call to the news server that tgenerates the formatted headlines box. Legal values are 'true' and 'false'.
