Question with flash remoting & the Result Object

Hello,

Every where I have looked for flash remoting tutorials and tips is using amfphp and not CFCs. I have everything set up correctly, I just cannot figure out how to get anything out of the result object.

I found an article that was saying I could get the number of columns by doing:
rs.serverInfo.columnCount;

However it produces this error:

TypeError: Error #1010: A term is undefined and has no properties.
at CustomClasses.roster::roster/::onResult()

I tried to access a couple other properties I found in some articles and I get the same error, can anyone tell me why this is happening?
