Hi script is below. The emailing part of the thing works fine, but the file isn't being output. Any clues?

As a side note to the advices you already received I would lkie to point out that although posting full code samples is more tolerated here than elsewhere (e.g. in clpmisc), it may be sensible to prepare properly trimmed down minimal examples still exhibiting the problem you're asking for help about.

A nice side effect is that chances are you find the solution yourself while doing so.
