RJ,
You have a common problem here. You are loading two mooTools js files into your template. One starts to set up functions and the other comes along and whipes them out.
You have the first load in your template:
ja_avian/_script_s/mootools.v1.1.js
The second loads with your moolet:
modules/mod_moolet_online_fb/mootools.v1.11.js'
We can know that our file is fully packed. If you did your own packing of the first file and are sure it has all the functions then turn off our file in the moolet control panel.
If you did not pack the file in your template and your template created did it, then it probably only has the functions your template needs and will not run the moolet.
If that is the case you could replace our file with thieir file, then turn of the js load in the moolet, or as a test just comment out the ja_avian/_script_s/mootools.v1.1.js in your template for now and see if the MooTools fires up the moolet.
