How to describe a function for current circulating in a coil?

In my model (Induction Heating) I want to represent the current that circulates in a coil through a time dependent function. I chose a function generated through value interpolation (figure). However, it is giving the following error:
- Feature: Stationary Solver 2 (sol1 / s2) Undefined variable. - Variable: t - Global scope Failed to evaluate variable. - Variable: comp1.Currentfunction - Defined as: comp1.Currentfunction (t / unit_s_cf) Failed to evaluate variable. - Variable: comp1.mf.coil1.ICoil - Defined as: (comp1.Currentfunction * unit_A_cf) * exp (i * phase) Failed to evaluate variable. - Variable: comp1.mf.ICoil_1 - Defined as: comp1.mf.coil1.ICoil Failed to evaluate expression. - Expression: d ((comp1.mf.ICoil_1-comp1.mf.coil1.Iint) * test (comp1.mf.coil1.VCoil_ode), {test @ 1}) Failed to evaluate Jacobian of expression. - Expression: (comp1.mf.ICoil_1-comp1.mf.coil1.Iint) * test (comp1.mf.coil1.VCoil_ode)
Could someone help me solve this?

If you are runing a stationary solve please change it to a time dependent. Because in a stationary solve, "t" is not defined. So try time dependent.
