I am generalising the twoPhase Euler Foam to handle n Phases . In the file pEqn.H I want to sum up the phase fraction of all the dispersed phases to get the dispersed phase . To do so I programmed the following :

PtrList<surfaceScalarField>alphaf(nPhases);                                                                                               
                                                                                                                                              
    //just an initialization                                                                                                                  
    surfaceScalarField af ;                                                                                                                   
    surfaceScalarField betaf = scalar(1) - af;                                                                                                
                                                                                                                                              
    forAll(alphaf,aPh)                                                                                                                        
    {                                                                                                                                         
        alphaf.set(aPh,fvc::interpolate(phases[aPh].alpha()));                                                                                
        af= af + alphaf[aPh];                                                                                                                 
    }                                                                                                                                         
    betaf = scalar(1) - af ;

On compilation I got the following error :
