in reply to Forms and interaction in CGI

Hallo Roman,

You say you need some forms and radio buttons, are you sure you are not looking to print HTML?
Have a look at, a tool which will help you print out HTML and parse submitted HTML forms.

I need a value (integer >0) stored in a variable. Like here:

Im not quite sure what you mean here, you need an integer stored in a variable?
$variable = 42;
Can you rephrase?

In any case, examples of doing this kind of thing, if I have understood your question correctly, can be found in abundance in the documentation.
