Twitter Not Connected

Using the sample code for Twitter with Corona, I keep getting the error message: “To develop for Twitter, you need to get an API key and application secret. This is available from Twitter’s website.”

But this keeps happening even though we have already assigned those values at lines 29-30 in Twitter.lua

consumer\_key = xxxxxx consumer\_secret = xxxxx

Any ideas why? This is happening also with the Twitter plugin in the plugin store.
