Thanks for you response. I had not realised that I could just click Finish& Merge. This does work when I open the Word Document manually.
However if the document is opened from within Excel, in the shape of the Word Icon at the bottom of my screen, and |I click on it, the "Mailings" tab contents are greyed out except for the "start mailing ". If I could overcome that I would be ecstatic!
