Why do you mean the amplifier have not the correct output (Ax)?

Can you more descibe? 

I think you don't know the difference to show the values in simulation and in Online-Test.

In the opened parameter fields under the blocks shows you the field Ax only the current values in the simulation.

To see the current values of the Ax of a block in the Online-Test, place the cursor on the block. Then popup a little pair of glasses near right of the block. Click on this symbol and it opens a field in that you can see the current value.
