There are multiple pages . On each page dynamic checkboxes. I check some checkboxes on first page i go to next page & check 2 more checkboxes . so when i return back to first page the checked checkboxes becomes unchecked. So how do i avoid this ? I need to write a loop to trap the checked checkboxes & pass it on to the page url so that when i come back to previous page the selected checkboxes should remain checked.

I am pasting the code of my checkbox below
<%
    Do While Not rs.Eof and Count < rs.PageSize
                  col1 = rs("ClientName")
  %>

<TR>
        <TD align=center bgcolor=white >&nbsp;<%=col1%>&nbsp;</td>

      <TD align=center bgcolor=white width=30%>
<TABLE cellSpacing=0 cellPadding=0 border=0 width=30%>
<TR>
    <TD width=60 bgColor=#ffffff align=left>
    <CENTER><input type=checkbox name="ap" value="y<%=rs("sitedetails")%>" > </input></CENTER></A></TD>

</TR>
</TABLE>
</td>
</tr>
<%
 rs.MoveNext
    Count = Count + 1
    Loop
%>
</table>

So if you see the checkbox has common name but different values i.e "Y" & record no (sitedetails).

Can anybody help? It's urgent
