Dear Amanda,

The constructor you are using for G4LogicalVolume is correct.

G4LogicalVolume( G4VSolid*             pSolid,
                     G4Material*           pMaterial,
                     const G4String&       Name, ...

It seems that one of the parameters you are passing to it is not of  
the type expected.
Likely the material  'Ar' is not a pointer to a material  ?

Else maybe you did not include the G4LogicalVolume.hh header file ?

If neither of these suggestions help, please look a bit more and then  
post the compiler error that you get.

Best regards,
