Excell Help needed

I need to learn how to use Excell Pivot Tables to pull data from a document into Excell. Anyone out there got those skills?

Also, I need to learn how to make Excell add times properly. Mostly minutes and seconds. I know there's got to be a way to do this, but Excell isn't the most blind friendly program for help.

Finally, I need to find out how to get Excell to round a number off instead of just truncate decimal places.

Help would be greatly appreciated.
