Please make sure you are only typing the date in using numbers - no special characters or spaces. There should be 8 numbers and the format to use is DD/MM/YYYY. Ex: If your son's birthday is April 5 2015, then you would type: 05042015

You may want to select and delete everything in each box before retyping, just in case there is a hidden space causing the problem.
