Display condition for dob

Hello to all.
Please I have a difficulty. I have the date of birth as a question and the following question is the patient's age. What is the answer to my expression for date of birth so that the age doesn't pop up as a question

Hi Basil,

Are you familiar with Hidden values? You can use these to make calculations in your form that will not be displayed to the user. So this would work well for you to calculate age once you have collected the date of birth. Check out this help topic for Hidden Values Tutorial Part 2: Calculations Using a Date. Once you get the idea of hidden pages, you can find age calculations in this help topic: Calculations with Dates and Times.

All the best!
