ezr->register('function') *very* confused

Hi All,

I understand the principal behind the way to manipulate data before it's output. However, once I've made my function where do I put it!? I'm using one of JV's output templates BTW. Anyway I made a fuction and I tried placing it in my script which calls ezr and I tried popping it into the template itself but no luck, I can't get anything to show up (no errors, just not showing up). Would someone be kind enough to illustrate an example of where to put the function and a sample call etc.
