I am struggling with the right loop code for my query. My data table resembles this example.

Table A
Cust_ID ,

So Table A will have the same Item_Num for the same Cust_ID but for different dates. I would like to build an array in one calculated field of the different dates. So the output would look like:

Cust_ID Item_Num Item_Dates
1 2 1/1/2011, 2/14/2011, 3/6/2011
2 2 3/14/2011
3 2 2/23/2010, 3/1/2011

Any help is greatly appreciated.
