well, I don't really know in a PHP context, but in my experience testing code through my job, when a single value is continually carried over into the wrong place over and over again, it either means the value call is directed to a single place rather than a variable location, or it means the variable is not reset after being assigned once. In this case it's probably the former and not the latter since it always seems to pick the second to last poster on the page even if that poster has not been selected already.
