Urgent help request, please pleeeeeease

I’m studying sound design and game music composition.
For a 3rd year university project I’m making music and SD for an ex students game.

So far so good, the music is flippin slamming and suits the game aesthetic.

Then I tired to make dedicated volume Faders using slider widgets.

My project is due on Friday and I’m banging my head against the wall tryna get those pesky Faders working

I’ve followed every tutorial out there and no dice… I’ve literally only used Wwise and fmod for audio in uE4 before now and it’s my inexperience using the software that’s to blame.

Please can somebody, Anybody! Give me a how to for an absolute noob?

It would be great to have the sliders in the pause menu, but at the start of the level is fine too.
