I was hoping that someone could please look at this and tell me what I am doing wrong. It will not display any results. I have looked it over but I cannot see why it will not display. Thank You.

Code:
function check_Grade()
{
	 var percent = document.gradeForm.percent.value;
	 //var percent = parseFloat(percent);
	 var absences = document.gradeForm.absences.value;
	 //var absences = parseInt(absences);
	
		if (absences >= 5)
			document.gradeForm.Comments.value = "You have an F because of excessive absentees";
		else if (percent >= 90 || <= 100 && absences <= 2)
		{
			document.gradeForm.Comments.value = "You have gained 3% to your percent for having few absences."/n"
			Your Grade: A, Your Percent: + percent * 0.3";
		}
		else if (percent >= 90 || <= 100)
			document.gradeForm.Comments.value = "Your Grade: A, Your Precent: + percent";
		else if (Percent <= 89.9 || >= 80)

			document.gradeForm.Comments.value = "Your Grade: B, Your Precent: + percent";
