I'm not an Excel wiz, but I have a file I created at work and it has 4 sheets to it that are accessible by the sheet tabs at the bottom. I emailed this file and several other multi-sheet files to my home and opened them up in Excel. The same exact Excel that is on my work computer. Same operating system, Win 7. BUT the sheet tabs at the bottom are gone on every file. Where did it go and how do I get it back? I can take this file back to work and the sheet tabs are there, back at home they are gone. Help!
