SELECT import_ind, po_type INTO L_import_ind, L_po_type
FROM order
WHERE order_no = :ORDER_NUMBER;
SELECT to_date(param_value, 'DD-MON-YY') INTO L_start_date
FROM param_detail
WHERE program_code = 'print';
IF (L_import_ind = 'Y' AND :ENTRY_DATE >= L_start_date AND (L_po_type = 2 OR L_po_type = 3))

At Layout view, select the image field and press F11 and write your code.
But if the item is the only item in the repeating frame, you may get error or wrong data.
Hope this helps
