I don't feel like typing a long message at the moment, so let's keep this short. This code isn't working: It's just a test, but I intend to use something similar in an functional module later, and that won't work if I don't know how to do this. You can see the error message here. It doesn't work because it's an "attempt to call method 'extensionTag' (a nil value)".

Do you see the problem? It's probably just something stupid I'm missing, but I don't see it. I tried doing it with callParserFunction as well, but that didn't work either.
