I have a problem when i try to simulate a circuit, I got the only straight line I don't know what is wrong can anyone give me hint !!!

What is the difference when I use SPICE or MULTISIM?

Please post your Multisim diagram for review.

Multisim its a Spice type analog simulators. The difference with other options is the interface and some of the advanced features.
