Regression - scenario won't run - can't determine why

[Harry]

Hi gang:

I am running a regression macro where I submit a X range of x variables, and
a Y range of Y data.

I make sure that my X range contains the same number of rows as my Y range.

However, when my x range (which is 15 variables) contains 15 rows, I get
this error:

Regression - the number of rows and columns in X range cannot be the same

Why is this? Is there a workaround?

thanks,
Harry
