bath fan (4 function) wiring question

Trying to wire a four function bath fan (vent,heat,light, night light) to two switches (three toggle and single switch) which will be side by side. their is 12/2 romex power running to the switches and two 12/3 wires running between switches and the bath fan. The bath fan is a Panasonic whispertone (FV-11 vhl).
The attached drawing is one option I tried and failed. I apologize for the drawing in advance. This is my last resort, my wife has lost patience with me. Thank you

Your diagram looks correct. What is the issue you are having? Does any of it work?

Switches seem to work starting/stopping power to unit when tracing with detector. Unfortunately, none of the functions work on the unit For instance, I will flip the main light switch and test where the bulb would go and it would test hot, but also the night light would test hot. Is something screwed up with my neutrals? I do not understand how power is getting to the unit, but not running anything. I also tried isolating the wiring to just the main light and that did nothing. Getting frustrated.

You said 2) 12-3 cables between switches and fan yet you are showing a 12-2 and a 12-3.

you are correct, I miss labeled the drawing. one wire is not used on the second 12/3 essentially making it a 12/2

It sounds like you are using a non-contact voltage detector. They are prone to false positives. Install the bulbs and fan motor and then test.
