Waves InPhase in Cubase

Hello there,

I have used InPhase in other DAWs before (mainly PT), but I am having a super tough time getting it to work properly in Cubase 8.5.

The problem is this - I have it in a track, and am using the Sidechain (via a Send) to compare the two. But the sidechain comes up empty.

Here is a quick screenshot (showing the Send, as well). Any tips for this?
