PCR -No band formation - (Aug/04/2010 )

I used the PV92 Informatics Kit from BIO-RAD to amplify the samples in the PCR. I followed the protocol as mentioned in the manual. After i ran the samples in the agarose gel, I could see only bands from the Molecular Mass Ladder(MMR), and migration of loading dye from the other wells. Is there any way I can check till what stage the protocol works and any idea as to why it is not working?
I have attached a picture of the gel after it was stained. The right most well was loaded with MMR (the one that has bands)
Thanks in advance for your help !!!Attached Image
