how to include more formulas to data valdation

i have written a formula for "k"(car type) column in data validation to change the displaying drop-down data list based on value of the "J"(No. of seats) column. i used "if" in data validation to do this. but i cannot write more repetition of "if" inside of the data validation. data validation dialog box do not allow to do this. so i cannot increase "No. of seats" data.


please help me to do in anther way. even by using macros
