Stupid question time. I installed the module and everything seems to work great, except the sidebox.

When I have the side box displayed, it shows the variable name, and not the variable.

For instance:
BOX_HEADING_SUBSCRIBE
BOX_SUBSCRIBE_DEFAULT_TEXT
HEADER_SUBSCRIBE_BUTTON

What did I do wrong? I'm guessing there's something I need to configure or I messed up and forgot to change a "YOUR_TEMPLATE", but I've gone through and can't find anything.

Any help?
