Displaying a text field based on a value in a table row of adobe forms



I have a requirement to display the text field (PO num) on top of the page, PO num is already there in the table which gets printed in the form. My requirement is to fetch the PO num from that table and display in a text field. Please note that in the table there can be no of PO nums but the text field always should contain the po num of the row which will be printed last in that page.
