The default (and for the example above) is set to be the > (greater than) HTML entity with a space on either side. Change this to whatever you want, but if the character has an HTML entity, be sure to use that. For instance, enter > instead of just >.

var linkHome = "/";				// In most cases, this value should just be a / sign. Or, you can use the fully qualified http://www.yoursite.com address if you'd rather. Basically, it just tells the script what all the link addresses will start with.

var hideIndex = true;			// Leave this value to true if you want the script to not list your index page name (index.html) at the end of the links path. The values true or false should be used, not inside quotes.

var UToSpace = true;			// Leave this value to true if you want the script to convert any underscores in directory or names to spaces. For instance, it would convert "golive_actions" to "golive actions". The values true or false should be used, not inside quotes.

var DToSpace = true;			// Leave this value to true if you want the script to convert any dashes in directory or page names to spaces. For instance, it would convert "golive-actions" to "golive actions". The values true or false should be used, not inside quotes.

var changeCaps = 0;				// This variable lets you change the capitalization of the directory and pages names in your menu. The value should be a number (0 - 3), and not inside quotation marks. Options are as follows: 0 = no change, 1 = Initial Caps, 2 = All Upper, 3 = All Lower

var hideExt = true;			// If set to true, this variable will not display the file's extension for any file names displayed in the menu. Otherwise, set to false to show extensions.
