To make a form sticky, You must predetermine the variables. A sticky form remembers the values that were entered into it. In this case, the benefit is that the browser remembers the information the user enters into a form. This is helpful for validation, and can prompt the user to complete the form if it was submitted incompletely.
This form is sticky because the variables are predetermined in the input section of the php code. All seems to be functioning properly because the code was entered correctly. If it wasnt, errors would be displayed in the HTML, and could then be corrected.
