My company is new to using Express Invoice via the web. We have access to the primary user and the information that she imputs via the web, but we cannot make changes. When I click record I get a message that says "All items with a quantity must also have a Description" when there already is a description. The primary user get a copy (draft) with no edits. What are we doing wrong? Is there something we did not set up correctly? Thanks, Melody
