Multiple dependant dropdowns using the same dataset

[DC81]

Hi legends.

I'm trying to make an app to keep a simple record of my tasks with a total hours at the end of it all. Dependant dropdowns are giving me a headache 😫 

Using the valid_if section for creating a dependant dropdown works great, but if there's multiple dropdowns drawing the data from the same sheet, every one (after the first) only offers the same list choices as above. My noob thoughts are telling me that if the column name is different then it would be an independant field. Yes?

How do I get around this problem?
