Hello again!I created a code from this example - to select a bunch of zip codes and then total up the population. I actually had this code working - doing exactly what I wanted to do - for almost a month. Then, I re-visited it, and for some reason it decided to stop working completely. The map doesn't show up anymore.Any ideas as to what happened?<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html;
