IF formula To Convert Months To Quarters

I created the following formula to convert a field with months (G:G) to what quarter of the year it falls in.

Formula:

=IF(G2={"Jan","Feb","Mar"},1,IF(G2={"Apr","May","Jun"},2,IF(G2={"Jul","Aug","Sep"},3,4)))

It doesn't work, how do I get it to work?



*Edit/Correction: I should probably check to see if the formula works in all the cells I want it to first.
