Add Total Length of Line Segments

Tom Moore
I am trying to use ImageJ to measure total linear extension of linear of a branching corals.  I have it setup and working but can not seem to figure out a way to get the results table to add up the total of the length measurements.

Can anyone provide me suggestions on a technique to sum the results in the results table.

Thank You
Tom

Tom,
 
This is slightly different methodology but the appracoh is the same.
 
Basically select the lengths from the results table, loop through the results and sum them up.
 
  // Skeletonize overlapping areas to generate single pixel lines
 selectImage(overlapMaskId);
 run("Skeletonize");

  // Measure overlapping area - Returns a list of perimeters (divide by 2 to get length from perimeter)
 run("Set Measurements...", "perimeter redirect=None decimal=7");
 run("Analyze Particles...", "size=10-Infinity circularity=0-1.00 show=Nothing display clear add");
 var i = 0;
  // loop though results        
  for (i=0; i<nResults; i++) {
       bone_apposition_perimeter = getResult('Perim.', i) + bone_apposition_perimeter;
  }
 bone_apposition_length = bone_apposition_perimeter/2;
 percent_bone_apposition = (bone_apposition_length/metal_perimeter)*100;
