Hi
you either have to preformat the cell as 'Text' or enter your values with a
preceding apostrophe. e.g.
'3-1

When I enter "3-1" in a cell, Excel changes this automatically to

the content of the cell changes to "37989", not the original "3-1".

How do I switch off this automatic formatting?

Thanks for any suggestions...
