[Users] Thorn for coupled equations

Hello everyone

I have been trying to write a thorn to couple the Klein-Gordon equations to the 3+1 Einstein equations. I can't figure out the details on how to make the thorn tell the ET how to update T_munu according to the evolution equations. I've been trying to write the thorn with Kranc without much luck, as Kranc isn't telling me anything when it does fail. I have attached the .m of the attempted thorn here. If anyone has any input or suggestions it would be greatly appreciated.
