I have code that needs to count a loop.

while loopEnd<loopStart count=0 loopStart=1 loopEnd=6 while loopStart < loopEnd count = count + 1 loopStart = loopStart + 5

          count=0 
          loopStart=1
          loopEnd=6
          while loopStart < loopEnd
              count = count + 1
              loopStart = loopStart + 5
          end

It looks like count gets set to zero any time this part of the code executes. count should probably be initialized earlier in the code.

If I understand you correctly, the second while loop should be above and as Christoph says it should also be initialized before. For example,

x=1;
while x==1
    %initilize those values here
    count=0
    loopStart=1
    loopEnd=6
    %go into the second while loop here
    while loopStart < loopEnd
        %%your other conditions here
        %%...
        %thenn the condition for grey and then increment count and loopStart
        if FL==128 && BR==128  % grey part
            motors (0,0)
            pause (0.5)
            motors (20,20)
            pause (1.5)
            count = count + 1
            loopStart = loopStart + 5
        end
    end
end
