Minitab/error/variables not of equal length

Am using Minitab 15 and working with existing Excel data set. Have manipulated existing variables in a variety of ways to create new variables. Some of these new variables have missing values, as do the existing ones. When I try to analyze two new variables such as in a scatter plot, and other ways, I get a "variables not equal length" error message. However, the variables are of equal length but do have missing values in them. This error does not occur if I work with two of the existing variables.
Thanks, RB
