Julie,
 You need to plot variable X vs. Variable Y for the scatterplot. So each
group should be in a seperate column (variable). More importantly, does
subject #1 in group 1 correspond to subject #1 in group2 and so forth?
If not, then the scatterplot is really meaningless. I see that you have
15 cases in group#1 but only 11 cases in grou #2. That's why I question
whether a scatterplot is what you really want.
