UDF to Define Temperature Dependent Negative Heat Source

      I am trying to calculate the average temperature of interface at each iteration (since I am solving steady state problem) and based on the interface temperature I want to update my negative heat source value (Q_Source=(-constant*(T_Interface-T_Constant))/volume). First, I tried UDM to store interface temperature but didn't work. Then I tried to GLOBAL variable to avoid UDM, but again no luck. I am using ANSYS FLUENT 2019 R2. For both cases, I Interpreted the UDF and during the interpretetion, FLUENT didn't show any error. I have attached my written UDF below. Can someone please help me to fix the problem?
