Hi everybody;

when I edit my work book of excel 2003, and click to save; a message appears that I should rename the file!
what is the solution?

thank you

Is this a file you are sharing with other users?

What's the exact message displayed?

the message says,"not exact but the same meaning"
your book is in read only mode if you need to save changes click yes to save in other name

thanks
