Well, I was thinking you could use parseNumber to convert the strings into
numbers. But you can do it manually too:
$('#bmiCalc').bind('submit',function(event) {
var feet = parseFloat($('#feet').val(),10);
var inches = parseFloat($('#inches').val(),10);
var pounds = parseFloat($('#pounds').val(),10);
var totalInches = (feet * 12.0) + inches;
var bmi = Math.round(((pounds / (totalInches *
totalInches)) * 703.0) * 10.0) / 10.0;
alert(bmi);
});
That will return the correct BMI result.
