UPDATE : Thanks to the comments, I figured out that the element has to be the first child of its parent to get selected which is not the case that I have.

It should also identify if an account has since been cancelled and mark the first instance of a cancelled record as "NEW". The code compiles, but whenever I try to test it by inputting an address, I receive "Error Code: 1054. Unknown column 'BillingRecords.Address' in 'where clause'" I feel like I've tried every fix for the column references under the sun (with

There's been various ideas popping up, like dispatchEvent etc but nothing that seems to be a clear, simple way of doing this.

Specifically, I want to 'spawn' an object and run a function within that object's class from my Main.as. The snippet I have at the moment is as follows; In Main.as: var object:class_Object = new class_Object(); object.spawn(); addChild(object)
