Sir,

I am facing this problem since 3 days..

I have 2 tables. Cards and CardTopics. cardtopic(field) is common to both the tables.

Problem.: When m clicking my next button it is not showing another question from "cards" table.

passing parameter from viewalllists.jsp to flashPage.jsp

   <td> <%=description%></td>
                                     <%-- <td> </td>  --%>
                                     <td class="vtd" align="center" >
                                     <a href="ListPage.do?pageName=2&iid=<%=Id%>"><img src="images/edit-icon.png" title="Click Here To Update This Lists" alt="Click Here To Update This Stream"></a>
                                         
                                     <a href="deleteList.do?method=deleteLists&id=<%=Id%>"><img src="images/delete-icon.png" title="Click Here To Delete This Cards"  alt="Click Here To Delete This Cards"></a>
                                         
                                     <a href="flashPage.do?cardtopicId=<%=Id%>&tname=<%=topicname%>&pageName=1"><img src="images/play.jpg" width="32" height="32"/></a>
                                     </td>

                                 </tr>
                              <%count++;
                                                }
