I've done the echo thing, thats how i found it was there. Its approx the 50th if statement in the raw event.

The more echos i added before that line (even made it echo over 5 lines, includind the line that numeric is on) and it echo'd them fine, and then stoped on the next 'if ($numeric'.

There are several if statements that take multiple lines, and one if statement thats not a numeric (for debuging).
