How can I calculate the sum of the quantity of a variable along time steps in Comsol??

how can I calculate the sum of the quantities of a variable along all time steps? in every time step the variable has its quantity and i want to know the sum of its different quantities from first time step to the last calculated time step.

Thank you for the answer, but I need the sum as a variable since I need the sum in my solution. Can I have the sum as a variable?
