I managed to make a similar applet but still needs more refinement to exactly match the one above. For me to do so, I would like to know the following:
1- how to shorten the text area height?
2- align the number "when entered" to the right?
3- adopt the same color of the 3rd text area as the background coz the one i had was white.
4-put the "compute purchase" button in a different panel under the previous one? I tried entering a new panel "p2" but when i browse it, it shows me only the "compute purchase" button as if it replaces the previous panel "p1"!!!
Thanks for your help.
