I didn't download your file, but if you want to display something like
'cut value must be between -4 and 4'
you can simply use fprintf:
sr1=1;x=rand(1,5);
fprintf(1,'cut value must be between -%d and %d\n',(length(x)-1)/sr1,(length(x)-1)/sr1)

message = sprintf('the cut value must be between -%d and %d',(length(x)-1)/sr1,(length(x)-1)/sr1);
uiwait(warndlg(message));
