There is a problem!
It looks like you did not enter a valid number for your age or height.
Remember, the height needs to be in inches or centimeters. For instance, if you are 5 feet, 4 inches tall and you want to enter your height in inches, you need to enter 64 in the height field because 5 ft x 12 inches = 60 inches, plus 4 inches makes a total of 64 inches.
Please try it again.
