I have had a browse at the various web pages that Andy has identified. However they are all pretty complicated and would require a lot of work to make them usable.
I don't think it would be time well spent to try and go down that road, especially since the coding in Access does, at the press of a button, precisely what I want. So my only difficulty is being able to adapt the red parts of the code in my first post to draw the information from the Query that I outlined in my last post. As you will appreciate I am not skilled in VB coding, so I do need a little help to edit the coding that already works!
