MaxNumber = 0

elif( n < minNumber ):
minNumber = n
Compatibility mode is so older or different versions of word all look the same regardless of its current version. So a lot of features you see in compatibility mode will be unavailable unless you upgrade. If you upgrade though be sure to uninstall the older version first. I hope this helped!!! Good Luck! :)
