Time dependent point heat source.

Hi Community,
i have run into a problem. I want to simulate cooling from cold water injection in a fracture. I have build an according geometry.
The mechanical side is handled by "Darcy's Law --> Fracture Flow / Point Mass source" with the term:
N0 = -int5(t)*mat4.def.rho
where int5 is a time-dependend flowrate in l/s, which is defined unter "Component1 --> Definitions". This part of the model works very well.
I wanted to handle the thermal side by "Heat transfer in porous media --> Fracture / Point heat source" with the term:
Qp = mat4.def.Cp * int5(t) * mat4.def.rho * (T_inj-T)*-1
However, for some reason starting the computation always returns:
Undefined variable. - variable t
For some reason the function int5(t) works fine with "point mass inject" but not with "point heat source". Do you have any suggestions?
