Change formula that removes blank cells to also exclude certain text from output list.

In the attached file (starting @ G470), I'm using the following formula to create a 'summation' of daily sales without all the blank cells:

Formula:

=IFERROR(INDEX($G$40:$G$466,SMALL((IF(LEN($G$40:$G$466),ROW(INDIRECT("1:"&ROWS($G$40:$G$466))))),ROW(G1)),1),"")

Everything works great except for, due to print-out formatting, I had to insert the column headers at each print page break, and hence the header text gets picked-up by the formula and gets included in the list. Is there a way to append this formula to exclude these headers?
