Embedded Excel Spreadsheet in MS Word Corrupted
 

I have a Word Template that has several embedded Excel spreadsheets in it.
This template is used by people who need to enter data then change it if
necessary. After entering information then going back into Word, some of the
spreadsheets often become "corrupt or no longer available". You cannot get
back into the spreadsheet to edit. And if you change the wrap options, the
embedded object becomes a picture.

Does anyone have any ideas as to what could be happening? I think it happens
after they have edited it a couple of times.

Thanks!
