IF formula

I am trying to create an IF formula which will be dependand on a number of variables. I have attached a sample of what I am doing. In Q3, I want it to return based on a number of potential conditions:

if N5 if greater than 0 and A5 if less than 32, ..... the Lookup shown
If N5 is greater than 0 and A5 is greater than 31, ..... the Lookup shown
(the above is working - I want to add the blwo conditions as well)

if L5 is greater than A5 and N5 if greater than 0 and A5 if less than 32, then same above look up however, instead of looking up

"O3/(LOOKUP(A3,'T&O Pay Scale - 322 - Admin'!$A$3:$A$23,'T&O Pay Scale - 322 - Admin'!$C$3:$C$23)),IF(AND(M3>0,A3>31),O3/(LOOKUP(A3,'T&O Pay Scale - 350'!$A$2:$A$22,'T&O Pay Scale - 350'!$C$2:$C$22)"

I want it to look up

"O3/(LOOKUP(L3,'T&O Pay Scale - 322 - Admin'!$A$3:$A$23,'T&O Pay Scale - 322 - Admin'!$C$3:$C$23)),IF(AND(M3>0,A3>31),O3/(LOOKUP(A3,'T&O Pay Scale - 350'!$A$2:$A$22,'T&O Pay Scale - 350'!$C$2:$C$22)"

Thank you for your help
