GetBrowserSelection doesn't count right.


I am working on a simple user interface to select waves to plot using the browser to select waves and then the command line to select the columns for x and y values.


In the data browser I have selected 5 waves.  The function returns only 3 traces and when I add the print statement to get the browser selection count it shows 3. So why don't these numbers match?  Data browser thinks 5 and getBrowserSelection thinks 3.
