Flash X & Y Coordinates Placement of MC

I am creating a dynamic contact form in FLASH MX and having difficulty in placing radio buttons in there proper Y position.  Because I have to create a new movie clip, the x & y positions are different than the root.  Is there simple solution for the proper placement of dynamically create mc within loop?

// ARRAY: DISPLAY NAME | FORM NAME | FORM TYPE
contact = [["First Name", "FistName", "textField"], ["Last Name", "LastName", "textField"], ["Company Name", "CompanyName", "textField"], ["Address", "Address", "textField"], ["City", "City", "textField"], ["State", "State", "textField"], ["Zip", "Zip", "textField"], ["Phone Number", "PhoneNumber", "textField"], ["Email Address", "Email", "textField"], ["WebSite", "WebSite", "textField"], ["Type of Inquiry:", "InquiryType", "textArea"], ["Comment:", "Comment", "radioButton"], ["How did you hear about us?", "HowHear", "textField"], ["Subscribe", "Subscribe", "checkbox"]];
function addTextFields(num) {
      iYoffset = 0;
      for (i=1; i<num; i++) {
            tempContactLabelVar = contact[i][0]+"1_txt";
            tempContactVar = contact[i][1]+"2_txt";
            trace(tempContactLabelVar);
            trace(tempContactVar);
            if (contact[i][2] == "textField" || contact[i][2] == "textArea") {
                  if (contact[i][2] == "textField") {
                        createTextField(tempContactVar, 100+i, 10, iYoffset, 150, 20);
                  } else if (contact[i][2] == "textArea") {
                        createTextField(tempContactVar, i, 10, iYoffset, 150, 60);
                        eval(tempContactVar).multiline = true;
                  }
                  eval(tempContactVar).type = "input";
                  eval(tempContactVar).textColor = 0x000000;
                  eval(tempContactVar).border = true;
                  eval(tempContactVar).selectable = true;
                  eval(tempContactVar).tabenabled = true;
                  eval(tempContactVar).tabIndex = i;
                  eval(tempContactVar).wordWrap = true;
                  eval(tempContactVar).background = 0xFFFFFF;
                  // add text decoration here
                  rf = new TextFormat();
                  rf.size = 18;
                  rf.font = "Arial";
                  FistName_txt.setTextFormat(rf);
            } else {
                  attachMovie("RadioButton", "RadioButton_mc", i);
                  RadioButton_mc._x = 10;
                  RadioButton_mc._y = iYoffset;
            }
            // CREATE FORM LABELS
            createTextField(tempContactLabelVar, 200+i, -70, iYoffset, 100, 60);
            eval(tempContactLabelVar).textColor = 0x000000;
            eval(tempContactLabelVar).text = contact[i][1];
            iYoffset = eval(tempContactVar)._y+eval(tempContactVar)._height+10;
      }
}
this.onLoad = function() {
      //Set here your X value
      addTextFields(contact.length);
