<SNIP> In the instance example, you'd use CreateObject and call init(userid) once. Then you'd call AddNewsLetter(newsletterid) 3 times instead. </SNIP>
I am going to have to look into this... I am venturing into the unkown. I have read up on CreateObject, but is was all abstract at the time. I will also have to look into init() and all the rest. It seems like the more I learn the more I need to learn. I know it will all pay off once it makes sense and I am writing code only once.
