my form works well so far. However, I am using the e-mail button which generates a XML in case the customer is pressed by customer. Moreover I want to fill customers e-mail subject not static with a plain text but with a text which is already present in a field. Unfortunately the "click" procedure which could be used to fill in a small code is gray, thus I cannot use java code with this e-mail button.
Another option would be to use a plain button and use Java in order to fill the right subject. But with this option it is not possible to generate and attach the XML file.
This has been asked and answered many times before. Just do a search (top right of this screen) for email subject and you will get numerous hits and suggestions.
