Hi

This is the first time I have posted so apolgies if I have done it incorrectly, however....

I recenly produced a series of workbooks that contained links to each other in the form of simple copy formulas. I produced this in a 2010 version but then proceeded to use it in 2007. The workbooks were thereafter listed as being in compatibility mode. Today I reopened the workbooks in 2010 again and converted all the files to the 2010 .xlsm format using the option on the file menu. It appears that some of the copy formulas have updated to recognise the new .xlsm format and some have remained in .xls and cannot link to the newly formatted workbooks. I have a feeling it may be something to do with absolute cell references but am not sure. Can anybody tell if and how I might simply convert all these formulas to recognise the new format without painstakingly altering all the individual formulas in each cell.

Thanks & Regards

Gianni
