Coding error?

I typed a document using Microsoft word processor and I emailed it but they cannot open the attachment. It said there was a coding error. Whats up with that?Coding error?
Some computers dont support some features. For Ex. a file saved in Microsoft Offics 2007 wont be accesible using microsoft word 2003. So i suggest you first change the file extension to something common or to .rtf (since most programs accept it).





Hope it helps
