Import Table for defining inflow concentration in transport of dilute species

Hi everyone,
I am working on a diffusion problem in COMSOL 5.1. I have problem with laminar flow in a pipe. The concentration of solute in the fluid varies over time. I have a table specifying the concentration at every time step. I need to import this table as the inflow for the problem. I was hoping someone could tell me how I could do that. Right now I can only see an option to define a single constant value for inflow.
I am a new user of COMSOL and would appreciate any help.

Create a interpolation function for inlet concentration as a function of time. In the table type in discrete time and concentration. In concentration on boundary type the name of function and argument as 't'

Thank you very much. That works.
