Syntax error THC Hydra? exactly what he says

hydra -l admin -P /root/Desktop/common.txt module: //s99031-101047-yvr.croto.hack.me/index.php http-post-form "/login.php:username=&USER&&password= ^ PASS ^ & Login = Login "

What's wrong with that? I get this error: either you use the module "www.example.com" [optional-module-parameters]" or you use the syntax "module: //www.example.com/optional-module-parameters"!

Thank you
