Query compile error.

Question

I know that both these queries work by themselves, yet when i put together, I get this error (i assume on the second query). Any thoughts?

Hi
See a trimmed down version of your code.
org.apache.jasper.JasperException: Unable to compile

<TD width="156" height="20"> </TD>
<TD width="178" height="20">
NumberOfPubs </TD>
</tr>
<%
%>
</table>You'll notice that you are redeclaring the varible rset & sql in the same scope. remove the second declaration but you can re-define tham as rset = null and sql = "....."; this should work
Good Luck!
