Table data in Adobe form

Hi Dear all:

    I got the mission to design an adobe form for pay slip. According to note 10006360. I copy the standard form sap_payslip_chq. In my own form, I need to change the outlook of the form. So I redesign the layout. But when I finished the form and test the form I found th errors. In the standard form it did not use table, just use text and text field in the subform. But it can get multi data. I used table, however I just get one data. I used the same interface as before in the standard one. What wrong with my form? Can anyone give me any advices? Thank you so much!
