Dynamic Stamps - Text Return as "Undefined". Why?

Hello...
I have a dynamic stamp with 4 checkboxes and 3 text fields plus a auto date field. The 4 check boxes and the date work well when I apply the stamp in a document. On the other hand, for the content of the text fields, the text returned by the dialog window returns nothing other than “undefined”. I can’t see what’s wrong... I need your advice before I hit my head on the computer! Thanks!

Below are my calculation script for the stamps in a separated field.

function Stamps() {
    var oJSDlg = {
        bChk1: null,
        bChk2: null,
        bChk3: null,
        bChk4: null,
        text1: "",
        text2: "",
        text3: "",
        initialize: function (dialog) {
            var oInit = {
                Chk1: this.bChk1,
                Chk2: this.bChk2,
                Chk3: this.bChk3,
                Chk4: this.bChk4,
                Text1: this.text1,
                Text2: this.text2,
                Text3: this.text3,
            };
            dialog.load(oInit);
        },
        validate: function (dialog) {
            var bRtn = true;
            var oRslt = dialog.store();
            return bRtn;
        },
        commit: function (dialog) {
            var oRslt = dialog.store();
            this.bChk1 = oRslt.Chk1;
            this.bChk2 = oRslt.Chk2;
            this.bChk3 = oRslt.Chk3;
            this.bChk4 = oRslt.Chk4;
            this.text1 = oRslt.Text1;
            this.text2 = oRslt.Text2;
            this.text3 = oRslt.Text3;
        },
