Trouble with combining And with Unique function

[diamondjoechubbs]

I am having some trouble combining some formulas using the unique feature. I was able to use an IF function with unique, but when combining IF and AND the function is not working

This one works with one criteria
=UNIQUE(IF('Tract Line List'!AK2:AK999>1,'Tract Line List'!$B$2:$B$999,""))

Using AND for two criteria, it does not return values the same way the single one does
=UNIQUE(IF(AND('Tract Line List'!W2:W999>1,'Tract Line List'!AK2:AK999>1),'Tract Line List'!$B$2:$B$999,""))

Thank you in advance

How about

=UNIQUE(FILTER('Tract Line List'!$B$2:$B$999,('Tract Line List'!W2:W999>1)*('Tract Line List'!AK2:AK999>1)))
