I posted it to a page to save and work on. I copied the chart you made,then posted the formula in column B of the chart and then received the error. I'm sure I did something wrong, so I recopied the formula in the formula bar,,,making sure it was exactly as you gave, still the same error. Here's a copy of what I posted, pressed enter and received the error. What am I doing wrong? I have Excel 2007 if that helps any.
