I've never been good at algebra

Question

I'm not quite sure what to search for so I can't find anything in the threads about this.  If you know of a thread just point me to it and I'd be much obliged.  Here is what I'm trying to do. I have 16 students trying to raise money for a trip.  The trip costs $500 dollars.  But, they are also allowed to raise extra money to cover the cost of a passport and a few other things.  I'm trying to get the table set up so that it will tell me how much the total group has left to raise for each person's $500, not counting when some people raise over that amount. The problem is that when I total everything up, the people who have raised over the $500 mess up the totals.  I can't find a function that will will figure up the sum of a row, only counting up to a certain amount per cell.  If that's not possible, I don't know quite what else to do.
Here's a sample of the table I'm working with.  Column B is a list of group fundraisers that we have done.  Column A is th total from those events.  Starting in column D is each student and how much they get from each group fundraiser.  The totals are at the bottom.  As you can see, Pete Rose has raised 150 dollars over the 500, which is good for him.  But I only need to count the 500 for my total group cost. So when I sum the grand total row, I need it to automatically subract the 150 out of his row, or only be able to add a max of 500 out of each cell. Otherwise the total is too high because there is extra money in the row not actually going towards the group cost.  I hope this makes sense.  If you need some clarification let me know.  Thanks for your help.

Answer 1

I'm not sure about wht formulas you have in the grand total row, but if you learn how to use the IF function, it allows you to test what your result will be, adn account for it. Assuming it was just summing a column of Data and you want to limit to 500, you could do the following:
=if(sum(D3:D10)>500,500,sum(D3:D10))
If will first test to see if it is more than the $500, if so, put in $500, otherwise put in the real sum.
