Does your method then try to do some sort of comparison, for example: if myparam \> 3 If myparam is nil for some reason, you might get that error. Try logging your input just after you get into the method. You may also want to log its class (e.g. myparam.class). ---

This really isn’t an Engines related question. You should probably be be asking this on the general Rails forum; removed\_email\_address@domain.invalid When you post there, please include the code that is erroring and the full error message - including stack trace. Without seeing the actual code, it is nearly impossible to determain the cause of the error in enough detail to explain it. ---
