Produced a workbook containing several worksheets and named ranges. A
couple
of columns containing formulas work OK on stand alone computer. However,
now
in use on a network of 20 or so computers the formulas in these columns
will
sometimes show #NAME? error message, even though on another terminal they
work OK.

I'm mystified and any help or leads would be much appreciated

Thanks
