   3               $4.00                    $18.00

   2               $7.00                    $44.00
   1               $6.00                    $34.00
   1               $6.00                    $40.00
   1               $4.00                    $44.00
   1               $6.00                    $50.00
   4               $5.00                    $26.00
   4               $5.00                    $31.00
   2               $6.00                    $50.00
   1               $6.00                    $56.00
   2               $3.00                    $53.00
				

Assuming that the category column is in column A, and the values column is in column B, and the headers are on row 1, the running category total formula at the top row would be:

   =SUMIF(INDIRECT("A2:A"&ROW()),"="&A2,INDIRECT("B2:B"&ROW()))
				

Copy the formula down for all rows used.
