[Click] testing qos using click !!

[Claude Hangui]

Hi everyone !!
I've been having compiling issues regarding a click code from the conf file.I have modified it a little bit to suit my purpose, I would like my router to guarantee qos for various kinds of data.I have started my tests by considering voip (eg skype audio call) and video streaming, with of course signalling for voip packets. I modified the "print-pings.click" file. Here it is :

FromDevice(eth1)                // read packets from device
                        

   -> Classifier(12/0800)            // select IP-in-Ethernet
   -> Strip(14)                    // strip Ethernet header
   -> CheckIPHeader       // check IP header, mark as IP
   -> ip :: IPClassifier(ip dscp cs5,
                         ip dscp ef,                 
                         ip dscp cs6,
                         ip dscp af31);
rr :: DRRSched
p :: PrioSched

ip[0] -> Paint(255,255,255) -> Queue(20) -> [0]rr -> BandwidthRatedSplitter(32kBps)[0] -> [0]p   // white colour for signalling packets
ip[1] -> Paint(255,255,0) -> Queue(25) -> AdaptiveRED -> [1]rr -> Shaper(1) -> [1]p  // yellow colour for network control 
ip[2] -> Paint(0,0,255) -> Queue(1000) -> [2]rr -> Shaper(10) -> [2]p   // blue colour for video streaming
ip[3] -> Paint(255,0,0) -> Queue(1000) -> BandwidthRatedUnqueue(128kBps,10ms)[0] -> [3]p // red colour for voip packets
   p -> ToDevice(eth1);

While compiling the code I get these errors : 

‘BandwidthRatedSplitter at 10 :: BandwidthRatedSplitter’ push output 0 connected to ‘p :: PrioSched’ pull input 0
‘BandwidthRatedUnqueue at 20 :: BandwidthRatedUnqueue’ push output 0 connected to ‘p :: PrioSched’ pull input 3
‘rr :: DRRSched’ pull output 0 connected to ‘BandwidthRatedSplitter at 10 :: BandwidthRatedSplitter’ push input 0
Router could not be initialized!

I've been trying to figure out what's going on for the past 2 days, but I'm stuck. I would appreciate some help from anyone. I would also like to know if I made a mistake with the Paint element. I know it takes integers as parameters, but when I checked on the internet I saw that colours are represented using red,green and blue (RGB). So I would like to know if I made a mistake by defining 3 integers for representing 1 colour int the Paint element

Thx again for your responses.........
