/providers/:region route isn't working

[cooperra]

When I went to http://textbelt.com/providers/us, output was

ReferenceError: providers is not defined at /home/ian/textbelt/server/app.js:92:12 at callbacks (/home/ian/textbelt/node_modules/express/lib/router/index.js:164:37) at param (/home/ian/textbelt/node_modules/express/lib/router/index.js:138:11) at param (/home/ian/textbelt/node_modules/express/lib/router/index.js:135:11) at pass (/home/ian/textbelt/node_modules/express/lib/router/index.js:145:5) at Router._dispatch (/home/ian/textbelt/node_modules/express/lib/router/index.js:173:5) at Object.router (/home/ian/textbelt/node_modules/express/lib/router/index.js:33:10) at next (/home/ian/textbelt/node_modules/express/node_modules/connect/lib/proto.js:193:15) at _middleware (/home/ian/textbelt/node_modules/authbox/lib/middleware.js:134:5) at Object.middleware [as handle] (/home/ian/textbelt/node_modules/authbox/lib/middleware.js:76:3)

but the code suggests I should be able to see a list of the loaded providers.

textbelt/server/app.js

Lines 74 to 77 in b9fb645

	app.get('/providers/:region', function(req, res) {
	// Utility function, just to check the providers currently loaded
	res.send(providers[req.params.region]);
	});
