MATLAB: Undefined function or variable ‘totalredCount’.

image processing

I am trying to obtain average values using the code below.
%for loop 
clc;
clear;
close all;
fontSize=10;
myFolder='G:\FYP2\Time Frames\Frame 15';
if ~isdir(myFolder)
  errorMessage = sprintf('Error: The following folder does not exist:\n%s', myFolder);
  uiwait(warndlg(errorMessage));
  return;
end
filePattern = fullfile(myFolder, '*.png'); 
theFiles = dir(filePattern);
numberOfImages=length(theFiles);
for k=1:numberOfImages
    fullFileName = fullfile(myFolder, theFiles(k).name);
    thisImage=double(imread(fullFileName));
    [rows, columns, numberOfColorBands] = size(thisImage); 
      %EXTRACT OUT THE COLOR BANDS FROM THE ORIGINAL IMAGE
      redBand=thisImage(:,:,1);
      greenBand=thisImage(:,:,2);
      blueBand=thisImage(:,:,3);
      %THRESHOLD LEVELS
      redThresholdLow=215;
      redThresholdHigh=255;
      greenThresholdLow=220;
      greenThresholdHigh=255;
      blueThresholdLow=240;
      blueThresholdHigh=255;
      redMask=(redBand>=redThresholdLow) & (redBand<=redThresholdHigh);
      greenMask=(greenBand>=greenThresholdLow) & (greenBand<=greenThresholdHigh);
      blueMask=(blueBand>=blueThresholdLow) & (blueBand<=blueThresholdHigh);
      yellowMask = uint8(redMask & greenMask);
      turMask = uint8(blueMask & greenMask);
      %Count pixels
      redCount=sum(redMask(:)>0);
      greenCount=sum(greenMask(:)>0);
      yellowCount=sum(yellowMask(:)>0);
      turCount=sum(turMask(:)>0);
      %Compute area fraction
      totalArea=rows * columns;
      redAreaFraction=redCount/totalArea;
      greenAreaFraction=greenCount/totalArea;
      yellowAreaFraction=yellowCount/totalArea;

          percentYELLOW=totalpercentYELLOW;

I don't know what that variable is supposed to represent, but you never assign any value to it before you try to use it in the line of code that throws the error. It's not defined yet so that's what the error is telling you.
