PHP "GET" Error?

Hi, 

    I have done something wrong here, because when I have my variables declared in my PHP:

   $people_from = $_GET['people_from'];
   $state_colors= $_GET['state_colors'];

  I get this url: http://localhost/generic.php?people_from=Adair, OK-Alfalfa, OK-Atoka, OK-Beaver, OK-Beckham, OK-Blaine, OK-Bryan, OK-Caddo, OK-Canadian, OK-Carter, OK-Cherokee, OK-Choctaw, OK-Cimarron, OK-Cleveland, OK-Coal, OK&state_colors=#FFFFCC-#FFFFCC-#FFCCCC-#FFCCCC-#FFCCCC-#FFCCCC-#FFCCCC-#FFCCCC-#FFCCCC-#FFCCCC-#FFCCCC-#FFCCCC-#FFCCCC-#FFCCCC-#FFCCCC-#FFCCCC

 The result? I don't get any colors on the screen as I have here in the url. 
However, if I do:
   
$people_from = "Adair, OK-Alfalfa, OK-Atoka, OK-Beaver, OK-Beckham, OK-Blaine, OK-Bryan, OK-Caddo, OK-Canadian, OK-Carter, OK-Cherokee, OK-Choctaw, OK-Cimarron, OK-Cleveland, OK-Coal, OK";
$state_colors= "#FFFFCC-#FFFFCC-#FFCCCC-#FFCCCC-#FFCCCC-#FFCCCC-#FFCCCC-#FFCCCC-#FFCCCC-#FFCCCC-#FFCCCC-#FFCCCC-#FFCCCC-#FFCCCC-#FFCCCC";

I get the correct result. In total, there are 77 entries (I only put 15 here). Is there a length limit for what I pass to the url? If not, how come there are no colors showing up in my image as I desired according to my url?

Thanks for your help.

Alice
