    Can anyone find anything wrong with this ??
    function gpv(gpvval)
	{
		alert ("this is gpvval ... " + gpvval + "")
		if (gpvval > 100)
		{
		gpvval = 'N/A';
		}
		if (gpvval <= 100 && gpvval >= 80)
		{
		gpvval = parseFloat(4.0);
		}
		if (gpvval <= 79 && gpvval >= 70)
		{
		gpvval = '3.5';
		}
		if (gpvval <= 69 && gpvval >= 60)
		{
		gpvval = 3.0;
		}
		if (gpvval <= 59 && gpvval >= 55)
		{
		gpvval = 2.5;
		}
		if (gpvval <= 54 && gpvval >= 50)
		{
		gpvval = 2.0;
		}
		if (gpvval <= 49 && gpvval >= 40)
		{
		gpvval = 1.5;
		}
		if (gpvval <= 39 && gpvval >= 35)
		{
		gpvval = 1.0;
		}
		if (gpvval <= 38 && gpvval >= 0)
		{
		gpvval = 0;
		}
		return gpvval;
		}

    Anything above 100 works but everthing else is just 0 ??

    Any ideas ??

    after using the if for your first statement, use else if's

    Nah ... tried that ... doesn't work !!

    I am thinking that it is trying to change gpvval to a float that is doing it.
    if i change all the other values to 'L/N' or 'Ted' or whatever it works fine ... so it must be the format.

    gpvval comes from the main code parseFloat(document.form.textfield.value) so i would have thought there'd be no problem when it was pass into the function but obviously there is ... even when i enter a float i.e. 85.21 it goes straight to 0 ..... i need to be able to pass a float back down to when the function is called.

    Anyone know how to do this ??

    function gpv(gpvval) {
		var gpa = 0;
		if (gpvval > 100) {
			gpa = 'N/A';
		} else if (gpvval >= 80) {
			gpa = '4.0';
		} else if (gpvval >= 70) {
			gpa = '3.5';
		} else if (gpvval >= 60) {
			gpa = '3.0';
		} else if (gpvval >= 55) 	{
			gpa = '2.5';
		} else if (gpvval >= 50) {
			gpa = '2.0';
		} else if (gpvval >= 40) {
			gpa = '1.5';
		} else if (gpvval >= 35) {
			gpa = '1.0';
		} else if (gpvval >= 0) {
			gpa = '0';
		}
		return gpa;
	}

    This is the one that works .... i dont know what else i did but its all good now !!
