Dialog in Illustrator CS4 js

Hi,

I have dialog script that I am using in InDesign to choose a pdf file to place into the document and I need exactly the same script in Illustrator, but  I have a hard  time to  translate it into Illustrator scripting format. I don't have much information about building dialogs in Illustrator. Could someone help me.

var myDialog = app.dialogs.add({name:"Holiday Templates",
canCancel:true});
with(myDialog){
//Add a dialog column.
with(dialogColumns.add()){

//Add a dialog column.
with(dialogColumns.add()){
   
    // Radius radio buttons //
    with(borderPanels.add()){
        staticTexts.add({staticLabel:"Choose Holiday Template:"});
        var myRadioButtonGroup = radiobuttonGroups.add();
        with(myRadioButtonGroup){
        var myEighthRadius = radiobuttonControls.add
        ({staticLabel:"4x6_flower", checkedState:true});
        var myQuaterRadius = radiobuttonControls.add
        ({staticLabel:"4x6_heart"});
        }
    }
}



    var myResult = myDialog.show();
    if(myResult == true){

var myFolderPath = myPath + "/~prepress/HolidayTemplatesFilePrep/";

        // Radio buttons readings //
        if(myRadioButtonGroup.selectedButton == 0){
        myTemplateA = File (myFolderPath + "/~4x6_flower.pdf");
        myTemplate2A = File (myFolderPath + "~4x6_flower_back.pdf");
        }
        else if(myRadioButtonGroup.selectedButton == 1){
        myTemplateA = File (myFolderPath + "/~4x6_heart.pdf");
        myTemplate2A = File (myFolderPath + "/~4x6_heart_back.pdf");
        }


        myDialog.destroy();
        myHolidayTemplates();
    }
    else{
        myDialog.destroy();
    }

}
}

Thank you very much for your help.
