Running the ET(electronic coupling) module

Clicked A Few Times
So I am new to NWchem and am trying to do CDFT calculations. I have been having some trouble with my systems so I thought it would be best to try something like electron transfer between two Anthracene molecules. I calculated movecs for electron transfer between two Anthracene molecules at 4 angstroms. I copied the movecs from these two seperate calculations to a new directory for doing the electronic coupling calculation. So with the movecs of the AminusA(left) -> AAminus (right) I tried to used the ET module to calculate the coupling. From my understanding of reading the manual the only inputs needed for running the ET model are the movecs. Here is what my input was.

vectors reactants left.movecs
vectors products right.movecs
task scf et

When I run this I get the error message.

et_calc: no geometry

What have I done wrong and what is the meaning of this error?

I am using 6.8.1.

solved issue
So I determined you do need to specify a geometry and basis when doing the coupling calculation. What I am confused about now is how one would specify a different geometry for the reactant and product states.

How did you fix the issue? I also need help in this. Can you share?
