RE: Define formula response not working?

There is no easy way to call into an equation or state of another script other than the SRAI operator.

For your FIRST THEN script you could just use a pattern.
Something like,

State:FirstThisThenThat { pattern "first * then *" template Formula:"{srai (get #word from :star at 1)}, {srai (get #word from :star at 1)}"; }
