Hi,

I try to operate FeynArts, I installed by

«FeynArts`

Then I typed

$ tops := CreateTopologies[1, 1 -> 2, ExcludeTopologies -> Internal];

$ InsertFields[tops, V[2] -> {F[4, {3}], -F[4, {3}]}, Model ->{SM}];

Here it gave an error

InsertFields::syntax: The syntax of InsertFields is InsertFields[tops, in -> out, options].

Any help to solve this,

Thanks,
S
