HiHiYou can start by putting long expressions in variables, eg.
SUM(
tracking[Amount] * (tracking[Type]=type) * (YEAR(tracking[Effective Date])=selected_year)
)
AND
SUM(
tracking[Amount] * (tracking[Type]=type) * (YEAR(tracking[Effective Date])=selected_year) * (Month(tracking[Effective Date]=selected_period))
)
The rest will be easy.
Can you upload the sheet without data or fake data? It will be easy to debug it.
I hope this helped.
