Thanks Graham,
I will give your suggestion a try when I get my laptop with the Excel 2010 system back tomorrow. By the way the macros will still operate fine - I didn't want to risk screwing up my live data hence I used a test workbook (different file name) with identical
worksheet names and data placement, but now I am happy with the code I would like to migrate it to the live environment - a sound way of working I believe.
In the meantime I was interested in your comment about XLSM and only being able to store macros in this file format. The reason I say this is I actually developed the macros and user forms in Excel 2007 and I've always used XLS as far as I can remember.
The macro works fine in my test data worksheet (XLS file type), and I can edit the code, modify it and store it all in an XLS file.
Do you know what is the real impact of the different file types (XLS and XLSM at least), or are they really only cosmetic and useful perhaps as a reminder?
regards, Bernard
