double document size

[Geppetto Luis]

I have this dialog box where I am told the width of the document

I would like this width to be automatically multiplied x 2

therefore instead of the value 3095
the value 6190 must come out

// script

var AD = activeDocument;  
var originalUnits = app.preferences.rulerUnits;
app.preferences.rulerUnits = Units.PIXELS;

var dlg = new Window('dialog','document size');  
dlg.gp1 = dlg.add('group');  
dlg.gp1.orientation = 'row';  
dlg.gp1.sTxt = dlg.gp1.add('statictext', undefined, ' ' + new UnitValue(AD.width.as('px'),'px') );  
  
dlg.btnGp = dlg.add('group');  
dlg.btnGp.ok = dlg.btnGp.add('button',undefined,'ok');  
dlg.btnGp.cancel = dlg.btnGp.add('button',undefined,'cancel');  
  
dlg.btnGp.ok.onClick = function() {  
app.preferences.rulerUnits = originalUnits;
dlg.close();  
}  
  
dlg.btnGp.cancel.onClick = function() {  
dlg.close();  
}  
  
dlg.show();

UnitValue(AD.width.as('px'),'px') * 2

Always kind
thank you

Line 3 sets the units as pixels, therefore I would have thought that:

new UnitValue(AD.width.as('px'),'px')

Is redundant and could be simplified to:

new UnitValue(AD.width)

Why make it px twice?

Kukurykus he answered correctly to what I asked but your note I find it right thank you
