Google apps script UI how to insert message into VerticalPanel()? - user-interface

Question

I'm trying to write this simple UI which should show a message with two parameters (name, email2send). But, when I run it, I get only this:
The content of the variable msg is not shown in the pannel, only the pannel title. What is the right way to do this?
// Show confirmation
function showMSG(name, email2Send) { // for ease of use I give the urls as parameters but you could define these urls in the function as well
var app = UiApp.createApplication().setHeight(60).setWidth(200);
app.setTitle("Msg send with sucess!");
var msg = "You request to " + email2Send + " a response from " + name;
app.add(app.createVerticalPanel().setTag(msg));
var doc = SpreadsheetApp.getActive();
doc.show(app);
}
THANKS in advance for any help!

The TAG of a widget is not visible, its purpose is actually to store string data in a way that is not visible.
To show a text use a label or an html widget.
example in your code :
function showMSG(name, email2Send) { // for ease of use I give the urls as parameters but you could define these urls in the function as well
var app = UiApp.createApplication().setHeight(60).setWidth(200);
app.setTitle("Msg send with sucess!");
var msg = "You request to " + email2Send + " a response from " + name;
app.add(app.createVerticalPanel().add(app.createLabel(msg)));
var doc = SpreadsheetApp.getActive();
doc.show(app);
}
