Tableau Formula to Power BI DAX

Could someone please help converting this to DAX.

"zn(if max([Quarter]) < 'value' then
if max([Segment Selection Flag Quarter]) = TRUE or [Segment Selection Flag] = TRUE then NULL else
zn(SUM({ FIXED [Quarter],[Geo],[Campaign BU],[Area]: MAX([GoalUniqueInteractions])}))
end
else
zn(SUM({ FIXED [Quarter],[Geo],[Campaign BU],[Segment],[Area]: MAX([GoalUniqueInteractions])}))
end)

"

Thanks,
Satish.
