SaveAs is not a function

Hello everybody,

i tried to a button in an Adobe Acrobat pdf form with javascript to automate the saveas function with the file name from a textfield.

I did a lot of research in the internet and found many examples and help postings so I know that I need folder level scripting because of security functions from adobe with the actual version of the reader.

folder level script:

myTrustedSaveAs = app.trustedFunction(function(vDoc,path)

{

app.beginPriv();

var myPath = "/C/Users/***username***/Downloads/test/" + "text1Value.pdf";

vDoc.saveAs({cPath: myPath, bCopy: true, bPromptToOverwrite: false});

app.endPriv();

});

button script:

var text1Value = this.getField("Objekt").value;

event.target.myTrustedSaveAs(event.target);

When I trie this scripts with the adobe reader it allways say "TypeError: event.target.myTrustedSaveAs is not a function" and I can't get that running.

Maybe someone can help me get this running

thank you for every help!
