How to properly use a variable in a resource string in extendscript

[danielsian.com]

I have the following code to build a UI in ExtendScript:

var dlgValues = new Object();
dlgValues.edittext = "string";
var dlg = "dialog {text: 'Test', alignChildren: 'fill', \
        panel: Panel {orientation: 'column', \
            group: Group {orientation: 'row', \
                et: EditText {text: "+ dlgValues.edittext +", characters: 40} \
            } \
        }\
         \
    }";
var win = new Window(dlg);
win.show();

I'm trying to use a variable dlgValues to input a value in a resource string UI but it works only if the input are numbers.

For example,

dlgValues.edittext = "string";

returns "NaN" in the EditText box instead of "string".

If it is a number, like

dlgValues.edittext = "3";

everything works well.

My question is: How can I use a variable to input string values in an EditText?

I'm not considering to access the text box using: win.panel.group.et.text = "string"

I found the answer by myself, I hope this is useful for someone struggling to find documentation about resource string.

Inside the resource script the variable must be surrounded by apostrophes in order to work with strings:

var dlgValues = new Object();
dlgValues.edittext = "string";
var dlg = "dialog {text: 'Test', alignChildren: 'fill', \
        panel: Panel {orientation: 'column', \
            group: Group {orientation: 'row', \
                et: EditText {text: '"+ dlgValues.edittext +"', characters: 40} \
            } \
        }\
         \
    }";
var win = new Window(dlg);
win.show();

dlgValues.edittext = "'string'"
