How to collect values?
How can I collect values from a form and display them in the same window? For example, to multiply your age by 3:
How old are you?
<---- Here must be there a text field where the user inputs a number, say, 19.
Click to calculate.
<---- Here must be there a button. The user clicks on it and the results must appear immediately:
Result: 57 <---- The result of multiplying 19 * 3 must appear here.
I'll appreciate your teaching.
Kirks.
