Query only recognized inside an If Statement?

Question

I have the following code in my JSP page:
If I place these line inside the if statement it works but
ie:
boolean temp = Get_field_data_1_rs.last();
If it is outside the if statement I get the following error:
ie:
boolean temp = Get_field_data_1_rs.last();
C:\\Program Files\\Allaire\\JRun\\servers\\default\\demo-app\\query1.jsp:20: Error: "Get_field_data_1_rs" is either a misplaced package name or a non-existent entity.
Any Ideas whats going on?
Code sample:
<% TableCount=1;
if (TableCount == 1) {
          String var_rest= "";
          if (Table_Array[TableCount][7].compareTo("") != 0) {
               var_rest = " WHERE " + Table_Array[TableCount][7];
          } else {
               var_rest= "";
     Statement Get_field_data_1 = report_data_connection.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_READ_ONLY);
     ResultSet Get_field_data_1_rs = Get_field_data_1.executeQuery("     SELECT " +
                                                                                     Table_Array[TableCount][4] +
                                                                                     " FROM " + Table_Array[TableCount][1] +
                                                                                     var_rest + " ORDER BY " +
                                                                                     Table_Array[TableCount][6]);
boolean temp = Get_field_data_1_rs.last();
int max_rows = ( Get_field_data_1_rs.getRow());
Get_field_data_1_rs.beforeFirst();
%>

Answer 1

// because statement was declared inside if,
// put it before if statement
Statement Get_field_data_1 = null;
if ( condition ..)
{  Get_field_data_1 = ....    }
else
