Quarter value as numeric numbers

Hi All,

Required a quick help in getting the quarter number as numeric format.

For example in attached screenshot, need to get the value for second line item as entered.

All Q1 Months should populate with numeric number 1, all Q2 should be populated with number 2 and so on....

Quartertodate() function gives a numeric number by month, but I need it by quarter.

Thanks

Madhu
