Need Help Populating single textfield with Dynamic Table data

Hello

I'm trying to fill a text field with data from a dynamic table. So I know how many item are in the table with the instancemanager.count function. I need help getting the data from the dynamic table and inserting it into one text field followed by comma.

Example:

               Dynamic table :     row[1]: DATA_01

                                            row[2]: DATA_02

                                            row[3]: DATA_03

                                            ...

I would like the textbox to automatically populate with the data in this format: DATA_01, DATA_02, DATA_03... and continue if there are more data.

I started with the code below but it doesn't do the job.                               

var Count = form1.page2.DATA_history.instanceManager.count;

var temp;

for (var i = 0; i<Count; i++)

{

    temp = xfa.resolveNode("form1.page2.PO_history[" + i + "]").DATA.rawValue;      // this seem to get the last row entry only.

    this.rawValue = this.rawValue + temp;                                                                  

}

I hope I was clear, but if anyone need clarification please ask. Thank you.
