Problem to get the values by this example

Hi following snippet, leads to an error:
Which says:

TypeError: undefined is not an object (evaluating '$$("queryForm3").getValues')
at line 14

My code:

var myForm = {
  id:"myform3",
  view:"form",
  elements:[
     { view:"checkbox",label:"Activ",name:"id2",value:1}
  ]
}


webix.ui({
    rows: [
      myForm,
      { view:"button", label: "Get Values",click: function (){
      	webix.message(JSON.stringify($$("queryForm3").getValues()));}
  		}
    ]
});

What do I’m missing?
Thanks for any help
Rolf

AFAICS, the only issue is the wrong ID: queryForm3 instead of myform3

Sorry I missed that, to much playing around
