Hello, '@variable' isn't useful because they aren't global. The global variable like '@@variable_global' could be used in a Web context ? What's happen when many user play with the application ? I've tried to follow your advice in the following code. Yes, I know that I 'm not good with HTML :( I've put comments in the code. I can't show the selected value in the form without reload the page !? Suggestions ? Tkanks.

You must RELOAD the page to see the previous selected values after the 'SEND' !!! ???
