Error in as.list(LIST) : object 'LIST' not found

[andrew...@yahoo.com.au]

I'm trying to a mediation analysis:

model.semantic2 <- 'ZGf ~ a*age
                Semantic ~ b*ZGf + c*age
                indirect :- a*b
                direct :- c
                total :- c + (a*b)'

fit2 <- sem(model.semantic2, data = data)

it returns the error message:

Error in as.list(LIST) : object 'LIST' not found

I can't figure out why, any tips?

Thanks

The operator you want is in the 3rd, 4th and 5th lines of model syntax is := , not :-
