I am trying to retrieve DIV 1, DIV 2, DIV 3 AND DIV 4 if the values meet the conditions of AND but it only returns DIV 3 even if the values don't meet the condition.

The If statement have created is as below

=IF(AND(O2<=6,V2<=6),"DIV 1",
 IF(AND(O2>=7,V2<=6),"DIV 2",
 IF(AND(O2>=7,V2>=7),"DIV 3",
 IF(AND(O2=9,V2=9),"DIV 4"))))

I want to get DIV 1 if cells O2 and V2 are less than or equal to 6,
I want to get DIV 2 if cells O2 is greater or equal to 7 and V2 is less than or equal to 6,
I want to get DIV 3 if cells O2 and V2 are greater or equal to 7,
I want to get DIV 4 if cells O2 and V2 are equal to 9.
