OpenOffice Error message

[Nicole1288]

I was using calc for a solid hour creating a complex page that was an addition to a multiple page spreadsheet. It went well initially and I printed out the finished page and saved it with no problems. When I switched to my laptop to post the document online the file will not load. I get a box that says "Read-Error Format error discovered in the file in sub-document content.xml at 2,177179(row,col)". What could cause this? Is there any way I can recover my work?

Such errors often arise because a document was also edited in MS Word. If you wish someone to look at it and attempt to repair the error (almost always successful in recovering most or all of the document), please upload it to the Forum, or if greater then 128KB, to a file sharing site and post the URL to this thread.
