There's no way to directly use STORE to output to a text file without headers. There are a number of solutions available using either macro's or an external vbs script or tool (e.g. sed). If you search the forums you should be able to find more information.
Thanks for your help. I'll abandon that idea and look at a button with a macro attached. Hopefully I'll get somewhere as what I'm trying to do is create a .txt file with one field in it and no headers.
