Having problems with #variable and Cursor in SQL 2008 - sql-server-2008

Question

--Not sure I am doing this right except what I am doing does not work. I have a list of (vend_num) that I need to run through a query one at a time and compile the results. If any can see/explain where I have gone off the rails it would be greatly appreciated. I have been combing the internet and this site and cannot seem to wrap my brain around it.
--drop table ##ENE_vendUpdate
if object_id('tempdb..##ENE_vendUpdate') is not null
begin
drop table ##ENE_vendUpdate
end
select vend_num
into ##ENE_vendUpdate
from vendor
--select * from ##ENE_vendUpdate

Your TSQL doesn't look complete. It should look something like this:
DECLARE warrwebcur CURSOR FOR
select vend_num from ##ENE_vendUpdate
OPEN warrwebcur
FETCH NEXT FROM warrwebcur INTO #vend_num
WHILE ##FETCH_STATUS = 0
BEGIN
-- your query
FETCH NEXT FROM warrwebcur INTO #vend_num
END
CLOSE warrwebcur
DEALLOCATE warrwebcur
