Revit multiple If function

[Mat.Syaf]

Hi, I need a help with the IF function. 
Here is are the situation,

(If No of Mod is 1)

If End Gable_Left is tick, No of Gable should be 1

If End Gable_Right is tick, No of Gable should be 1

If both End Gable_Left & End Gable_Right are tick, No of Gable should be 2

If non is tick, No of Gable should be 0

(If No of Mod is 2)

If End Gable_Left is tick, No of Gable should be 2

If End Gable_Right is tick, No of Gable should be 2

If both End Gable_Left & End Gable_Right are tick, No of Gable should be 3

If non is tick, No of Gable should be 1

(If No of Mod is 3)

If End Gable_Left is tick, No of Gable should be 3

If End Gable_Right is tick, No of Gable should be 3

If both End Gable_Left & End Gable_Right are tick, No of Gable should be 4

If non is tick, No of Gable should be 2

until now, if No of Mod is 2, I able to make No of Gable turns 2 if either Left or Right is tick. But if both Left and RIght is tick, the No of Gable is still 2, not change to 3. 😖

AND Conditional Statements:  

if(and(End Gable_Left, End Gable_Right), 2, if(and(not(End Gable_Left), not(End Gable_Right)), 0, if(and(End Gable_Left, not(End Gable_Right)), 1, 1)))

Note the OR Conditional Statement as well.  It's constructed the same way as the AND Conditional Statement.

if(and(End Gable_Left, End Gable_Right), No of Mod + 1, if(or(End Gable_Left, End Gable_Right), No of Mod, No of Mod - 1))
