You need a minimum screen resolution of about 700 pixels width to see our exercises. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.

Add the form called frmNewHeart in the folder above into your project (or use one you already have).

Delete the textbox for entering this person's age, and replace it with a NumericUpDown with appropriate minimum, maximum and increment values:
