.....anyone cracked this simple one?

I have an Excel spreadsheet which contains a mailto hyperlink in one column,
& in two other columns on the same row I have text that I want to use to form
the mail subject - ie when the hyperlink mailto edit box is displayed, in the
'subject' text box i really want to input a reference to an Excel cell.

Is there any easy way this can be done? I appreciate that I can probably
work around it using VB, but I would have thought a simpler solution may
exist.
