cant create file

[Sue]

Hello I am a novice with Excel and have a problem when trying to open an
Excel attachment. I receive the following message:

"can't create file : hendon.xls. right-click the folder you want to create
the file in, and then click properties on the shortcut menu to check your
permissions for the folder."

I can however open other excel attachments wihtout any troubel so I am very
confused.

Any assistance gratefully received

Thanks Sue
