Unlike <apex:actionSupport >, which only provides support for invoking controller action methods from other Visualforce components, <apex:actionFunction > defines a new JavaScript function which can then be called from within a block of JavaScript code.

I'm stuck on my rendered argument here - I'm fairly positive i'm pulling values from the record itself and not from the visualforce page. When I change the value (are_you_kp__c) from the record to a "No" - the pageblocksection shoud render, but for some reason it doesn't.
