var mCOLOR = "#ADD8E6"; // main nav cell color
var rCOLOR = "#ADD8E6"; // main nav cell rollover color
var bSIZE = 1; // main nav border size
var bCOLOR = "#696969" // main nav border color
var aLINK = "#696969"; // main nav link color
var aHOVER = ""; // main nav link hover-color (dual purpose)
var aDEC = "none"; // main nav link decoration
var fFONT = "arial"; // main nav font face
var fSIZE = 13; // main nav font size (pixels)
var fWEIGHT = "bold" // main nav font weight
var tINDENT = 7; // main nav text indent (if text is left or right aligned)
var vPADDING = 7; // main nav vertical cell padding
var vtOFFSET = 0; // main nav vertical text offset (+/- pixels from middle)

var keepLIT = true; // keep rollover color when browsing menu
var vOFFSET = 5; // shift the submenus vertically
var hOFFSET = 4; // shift the submenus horizontally

var smCOLOR = "lightblue"; // submenu cell color
var smOPACITY = 60;
