Please be aware that if you are using Microsoft 2007 you may not be able to upload Word documents into your job cart without converting the document from a .docx file to a .doc file. Save your .docx file as a .doc file and you should be able to upload into your job cart. 

This is also the case if you are using any software other than Microsoft.  Wisc.Jobs only allows Microsoft .doc or .pdf files to be uploaded.
