Trying to make this circuit in simulation ??

am i doing it right ?? help me out !!!

You did not wire the circuit correctly, here are the changes you should make:

1.  V1 and V2 in the diagram represent two different voltage signals.  You can use two function generators or use two AC voltage sources, these are located in Multisim component database Sources group, Signal Voltage Sources family

If you use the function generator, connect the middle pin to group and the + pin to your circuit, the - pin can be open.

2. Connect the opamp + pin  to ground exactly like the diagram

3.  Most opamp you see in textbook shows 3 just like this diagram, but in real life you need to power the opamp with DC sources and you need to do that in Multisim as well.  In Multisim, connect pin 4 connect to a negative DC source and pin 7 to positive.  The DC power source is located n the Sources group, Power Sources family.
