Default Cursor Error

I am using SQL Server 2000 with ASP 3.0
I got a cursor error:
"Microsoft OLE DB Provider for ODBC Drivers error '80040e14'
[Microsoft][ODBC SQL Server Driver][SQL Server]A cursor with the name '_cursor_courses' already exists. "

 My SQL Statement:

DECLARE _cursor_courses CURSOR


SELECT dplan_aa.course_code
course_info ON dplan_aa.course_code = course_info.course_code INNER JOIN department_info ON course_info.department_id = department_info.department_id
WHERE (department_info.department_id = 'LIB')

    OPEN _cursor_courses
    DECLARE @course_code varchar(50)

    FETCH NEXT FROM _cursor_courses into @course_code
    WHILE (@@FETCH_STATUS <> -1)
        IF (@@FETCH_STATUS <> -2)
            DECLARE _cursor_learner CURSOR
                    SELECT dplan_aa.learner_id
                    FROM dplan_aa INNER JOIN learner_programs ON dplan_aa.learner_program_id = learner_programs.learner_program_id
                    WHERE (dplan_aa.assigned_course = 0) AND (dplan_aa.course_code = @course_code)

                    DECLARE @learner_id char(10)
                    OPEN _cursor_learner

                    FETCH NEXT FROM _cursor_learner into @learner_id
                    WHILE (@@FETCH_STATUS <> -1)
                            IF (@@FETCH_STATUS <> -2)

                            INSERT INTO tempRemainingCourses
                                                ( course_code,
                                                    learner_id )
                            VALUES ( @course_code,
                        FETCH NEXT FROM _cursor_learner into @learner_id

                    CLOSE _cursor_learner
                    DEALLOCATE _cursor_learner

            FETCH NEXT FROM _cursor_courses into @course_code

About 4 out of 10 time I get the error above but 6 out of 10 times everything runs fine.

What could be wrong???
Please help.

Do you close and deallocate the cursor "_cursor_courses"?

I obviously don't know the full requirements and structure of your database but it seems to me you could do these inserts using standard SQL without resorting to cursors at all.
