generate PDF Title from textfield

[Fadmir]

Hello everyone,

this is my very first post in this forum!

Description of the problem:

I want to set the input from a textfield as the documents new filename after pressing a button which is programmed as following:

var berichtsname = this.getField("Berichts Nr").valueAsString;
app.browseForDoc({
bSave: true,
cFilenameInit: berichtsname + ".pdf"
});

The problem is that the user can't select a file type in the drop-down menu (it's just empty).

To make this clear:

I want the title of the open pdf-file to be changed to the input of the textfield "Berichts Nr".

This is important because I want to automatically send the file with the new name via email, which works just fine.

Thank you for your help
