Mistake in SPL

So basically I wrote out the headings for SPL and then I did the workings. Then I realized that I forgot to add an operating expenses section. Like after Gross Profit I had immediately wrote Profit from operations. I added a little comment on the side to the gross profit saying (after gross profit: operating expenses = ) and then I also added the calculation near the profit from operations showing how I got to that figure ($x Gross Profit - $x Operating Expenses). Will I still get the marks for it? I had no idea how to add another row in the spreadsheet and none of the invigilators did either so that was my last option.
