[Heat transfer3.5a] imported function like boundary condition

I need an analysis with boundary temperature change. I know temperature variation with seconds.
For example I know time vector[0 10 20 30] (seconds) and T[50 80 90 75] i insert this data in a function called my_T.
At the end I go to options->expression->and I define support_T in variable name and my_T in expression,
the last thing that I make is to assign in boundary condition in Temperature space: support_T.
I launch the stationary analysis but I find the following error: Failed to evaluate variable:support_T and failde to evaluate my_T.
Thank you in advance

Watching on discussions i think that I find solution but I am not sure.
I try to work with a simply model and i obtain a result.
In fact if I insert a function f(x), called my_F, where x is the time, it is possible to obtain results inserting my_F(t) in boundary conditions. In this way I can launch transient analysis and obtain results.
If someone knows better way to work please tell to me.
Thank you
