Quick glance at Joomla code, query not working...

I am working on a small joomla project as I am a bit stuck and need a second pair of eyes to look over a few lines of code that are not working. Any php or joomla expert should be able to see this in minutes. The page is in joomla, but the table in an external pluggin called amember. I have attached the file in question. the query that is not working is between lines 109 - 132 Please only bid if you have time to look into this, and are able to troubleshoot this. I will pay $20.
