There's an Excel function for almost everything — you can sum or average a range of values, and you can even let Excel decide what values it evaluates! But when a lone function simply can't get the job done, Excel needs a little help. That's the case when summing the top n values in a range. This week, tell us how you'd sum the top n values in a range. You'll need more than a single function. Last week we asked: Why can't I add comments to this document? Perhaps this one was just too easy, because no one took the challenge last week. This situation really did occur. Someone sent me a document for review, but I couldn't add comments. For a second or two I was a bit puzzled, but I quickly discerned that the document was protected. I was able to unprotect the document by choosing Unprotect Document from the Tools menu so I could then enable the reviewing tools. Initially, I thought I was in for a bit of work. What in the world was wrong? Fortunately, good sense kicked in and I checked the protection setting. It just goes to show that most problems usually have a simple solution, if you just know where to start looking.
