[immortality]

I've written these two functions:

massflow_left
    {
        type            faceSource;
        functionObjectLibs ("libfieldFunctionObjects.so");
        enabled         true;
        outputControl   timeStep;
        log             true;
        valueOutput     false;
        source          patch;
        sourceName      left;
        operation       sum;

        fields
        (
            phi
        );
        factor 1;
    }

massflow_right
    {
        $massflow_left;
        patchName right; 
    }

but the function massflow-right still performs on left patch(writes the left values).why?!
