hi stefanh, so is there other way to done it without CDT manipulation? i.e using function. So far i found out that month() function returns integer and with apply(), it can become an array of submitDate in integer. From there on I'm stuck at how to construct an sum array that consist of the sum of the same number in the previous array. i.e. from submitDate array {1,1,1,1,2,2,2,3,3,4,4} to am array of {4,3,2,2}.
