How is it possible to look at a net value ?

Hi,

I am a beginner and I want to do a volume control using a decibel look up table.

Here is the schematics:

For the moment I enter a fixed value as input for the lut.

When I look at the program, I can see only the look up table

We can see the lut, the input value but the ouput value does not appear. The multiplier does not appear neither.

How it is possible to see the output value of the lut?

I suppose there is a command to see the value of a net , isn't it?

Thank you for your help.
