How to use slider inside a UI dialog.

cTID = function(s) { return app.charIDToTypeID(s); };
sTID = function(s) { return app.stringIDToTypeID(s); };

function test() {

function step1(enabled, withDialog) {
if (enabled != undefined && !enabled)

var dialogMode = (withDialog ? DialogModes.ALL : DialogModes.NO);
var desc1 = new ActionDescriptor();
var ref1 = new ActionReference();
ref1.putClass(cTID('Lyr '));
desc1.putReference(cTID('null'), ref1);
var desc2 = new ActionDescriptor();
desc2.putString(cTID('Nm '), "AJUST");
desc2.putEnumerated(cTID('Md '), cTID('BlnM'), cTID('Ovrl'));
desc2.putBoolean(cTID('FlNt'), true);
desc1.putObject(cTID('Usng'), cTID('Lyr '), desc2);
desc1.putInteger(cTID('LyrI'), 11);
executeAction(sTID('make'), desc1, dialogMode);
};

if (enabled != undefined && !enabled)
return;

desc1.putUnitDouble(cTID('Nose'), cTID('#Prc'), 40.52);
desc1.putBoolean(cTID('Mnch'), true);
desc1.putInteger(cTID('FlRs'), 71345231);
