If the math is done right, you may indeed have a negative figure.
Line one: Line on are your gross receitps that you have received from doing business operations.
LIne 2: Then you enter any returns and allowances you gave to customers.
Line 3: You subtract the returns, allowances (i.e. refunds, etc) from the gross receipts (line 1 - line 2). This will yield a net receitps.
Line 4: is where you entre the cost of goods sold. Hopefully, the cost of goods sold, taken from line 42 of page 2, would be less than your income. For example: If you have your price point right, the a product that cost you say,, 16 dollars to make, would be selling between 26 and 36 dolllars. However, in some industries, such as the car industy, the margin is only 5%. It is possible to sale things at a loss, especially for a new business.
In line five: you subtract tract the cost of goods sold which you entered on Line 4 from your entry on line 3, which hopefully will yield a positive nubmer. However, in your situaion, you will have a negative number. (or gross loss rather than a gross profit).
