Why is it that when I send call this function: function GetNextDate($whichfriday, $month = "", $frequency = 1, $basedate = "")
with this line: GetNextDate("4", "2003-03", "5"); that $frequency ends up ""? Whether I set it myself when I call the function, or I leave it blank and let the function set it itself, it ends up with nothing in it. empty() returns 1, while isset() returns nothing on this.
