thanks for the help, i understand what and how you are doing it and
had the output variables in my stored procedure at one time, but the
if statement was my downfall. I showed the guy that told me to create
the procedure and said it was coming along but wanted me to setup if
there was an error(i am guessing any error) that he wants an email
generated with the error sent to him. I am at a complete standstill
till i figure that one out.
Thanks for the help I do appreciate it.
