Time and Temperature dependent material properties

Hi everyone, Still a COMSOL newbie so this might be a very simple question. I am running a time-dependent heat transfer model. In my model, the thermal conductivity of the material changes with temperature (T3) (which changes with time since this is a time-dependent study). I wrote a simple analytical function and used that as an input to the material properties. See screengrab. As you can see, when I plot the analytical function, it looks fine.
I can run the model fine too. However, when I plot the thermal conductivity, I do not see any fluctuation with Temperature or time. I assume that I have somehow not coupled the material properties to change with time and temperature?
Any tips highly appreciated.
