Born Haber cycle for enthalpy of solution (ACCESS)

Can someone check this is correct? My assignment needed me to draw the diagram below from the values provided. Is the equation correct, I have a friend who has it as exothermic. Which is correct?

that diagram is correct I believe, but it doesn't necessarily help to find the question mark value, which is the 2nd electron affinity of S-, there should be other information to help you to find that out, which is likely to be a positive value.

Thank you, I didn't need to find the ?, just the enthalpy of solution. There were some extra values for another Born Haber cycle that i've already done.
