One other thing to check is EXACTLY what the value is that you are testing for - in particular, look at a hex dump of the packet (or a decoded version of it). I've been caught out with things like trailing nulls, so it's 6 bytes of "value"0x00 not five bytes of "value" and the matching in dhcpd is very precise on this - they don't match.
