Problem executing while loop

Hi everyone,

Thanks in advance for your help.

I am having trouble getting a while loop to work. I am trying to make 20 plots, but only the first plot is made and nothing else.

Additionally, I use the exact same while loop/FileCounter code in a separate script and it works fine to make 20 plots. When I add in the snippet to plot below to the working code, an error comes up about a completely random section of code and even if I delete the new code the error still shows up and I have to close matlab in order to run the original, working code. But may be beside the point.

data_AM = ('<path>');
data_PM = ('<path>');
DataFilesAM=dir(fullfile(data_AM,['*' '.cdf']));
DataFilesPM=dir(fullfile(data_PM,['*' '.cdf']));


FileCounter=1;

while (FileCounter<=20)

%Read in all files/give variable names
    
     t=temp_AM;
     td=dp_AM;
    for i=1:length(height_AM)
        t(i)=temp_AM(i)+273;
        td(i)=dp_AM(i)+273;
        es(i)=6.11*exp((2.5*10^6/461)*((1/273.15)-(1./t(i))));
        ws(i)=(0.622/pres_AM(i))*es(i);
        w(i)=(rh_AM(i)/100).*ws(i);
    end; 
    figure(FileCounter)
      h=(height_AM);
      plot(w*1000, h) 
      set(gca,'YLim',[30.5 4000]); 
      
      
    FileCounter=FileCounter +1;
end

Any suggestions? I appreciate the help!
