Adding fields using VBA in Access 2007

In my database there is a table called "tbl_Shrinkage" which has the LineNumber, YearMo, HDLR fields that I need to use to tell the vba code what to add.  If the "YearMo" and "HDLR" and the line number is between 1 and 6, I need to total up the Prod_Lbs, SK_LBS, BF_LBS and put it in a table called "tbl_PutDataInto" and in that table for the line number field update that to a 7.  Essentially the YearMO and the HDLR fields have to be the same ie. I want the totals for Prod_LBS, SK_LBS, BF_LBS  for line 1 thru 6 for 201201 (the month of Jan.) for HDLR 020 and put it into a separate table using VBA.
