add a second independent variable, doing regression in excel?

I would like to add a second independent variable in a regression analysis
using excel. When I click on data analysis, then regression, there is only
cells for one x-variable. The help says you can have as many as 16. Must be
some simple process for adding additional variables. Hope someone can help. I
am a compete novice at this one.
Thanks, Cheeks

Excel is asking for one X matrix, consisting of up to 16 columns (variables).
