[Multisim 10.0- student edition]

i currently doing my project and need to do some simulation on it. i need to simulate a motor driver by using L298 IC, however i cant find this ic in the library of multisim, so i make my own component. However, when i connect it to the function generator to generate the pulse, it pop up some error.
can someone give me some hand by telling me how to solve the problem
thanks.

i already attached the error message and the schematic drawing that i draw
