Hi guys I just bought my first MacBook, and I'm slowly adjusting to the platform. It's all great, but I have a really big issue in Excel 2011, when trying to create a simple scatter chart. When I try to plot in the x and y values I get the following message: "The formula you typed contains an error" I have never experienced this in Excel 2010, and I have NO idea why I get this error? Can someone please help me? I have an exam coming up soon, and I have to be able to make these charts.
