The solver’s counting on the setter, indeed! (5,7,2)

Ross

I believe the answer is:

youre telling me

'indeed' is the definition.
(both can be used to express agreement)

I cannot understand how the remainder of the clue works.

(Other definitions for youre telling me that I've seen before include "agree entirely" , "I am getting your message" , "Solver's instructing setter" , "I should say so!" , "I couldn't agree more" .)

I've seen this clue in The Times.
