graphs in Access Reports

[Sale Humo]

I am using Microsoft Office 2000

Any time I try to insert a Graph in my report I get the following error msg:
"Microsoft no puede encontrar el objeto OLE vinculado que intentó actualizar
usando el comando vinculos OLE/DDE"

I'm sorry the msg is in spanish, but I think it means more or less that
can't find the link OLE object which is triying to update.

Thank you very much
