Formula to only add negitive numbers in selected field

Hey Forum,

I need a formula that only selects the negative numbers in a cell block and adds them up. Would this be a DSUM or a SUMIFS formula? It seems like that would be the right function but I don't know how to enter the parameters in the equation. The Data would need to compile in Cells C37 & C38 tab AIA 1!. The data for C37 would be pulled from AIA 2! D29:38. The data for C38 would be pulled from AIA 2! E:F29:38.

Thanks all for any help you can give!

Okay its adding everything properly! awesome! Thank you so much

I just need one last piece. How do I modify that formula so that the cell is blank unless there is data there to meet the parameter of SUMIF("<0"). Would it be along the lines of =IF('AIA 2'!D29:38=">0","",SUMIF("<0")). It won't take that but maybe I'm on the right track? lol

Hey Benishiryo,

Thanks for the quick response! I could run an example in those columns if that would help. Let me see if that works first, I'll let you know.

That almost works but I need it to be if =0 negitive numbers, not just any number. Is there a way to specify =0 ">0","", ? something like that?

Well here is what you have helped me build so far . I am very happy for it, thank you so much for your help. I attached an older version to my first post Idk if you saw it or not.

I have one last piece I wanted to try and add but I don't know if it is possible. if you look at AIA 2 you'll see columns labeled C,D,E,F,G.

Column C is the contract amount
Column D is what was paid on the contract last month
Column E&F are what is being requested this month

What I would like is if I could somehow have excel recognize if the added amounts in D,E,& F are greater than the amount in Column C, and if it is display "ERROR" or something like that.

Here is where it gets a little harder. I will be sending this form to a lot of my sub contractors once its complete. I need them only to be able to enter a number in that cell, not be able to edit the function, because they will accidently delete something and I'll be getting phone calls all day, and messed up forms.

I have locked and hidden ever other cell except these, as these cells are the only areas in which they need to input data. Hoping for a little more magic! Thanks man! I've already been able to adapt a lot of the stuff you taught me to other applications its much appreciated.

I tried this in cell D12 but it wouldn't take it.

=IF(SUM(D12:F12)>C12,”ERROR”,D12,)

I also tried using data validation on the G column, since the G column is the sum of DEF (Whole number less then or equal to C12) , but it only works if I open the G cell to edit and then hit enter. Otherwise it just allows it to run over the amount.
