Hi
i can't understand what you are going to achieve because there is not much information about your formula
first i would like to remind once again please read the 3 sticky Green Key before posting
http://chandoo.org/forums/topic/phd-forum-posting-rules-etiquette-pls-read-before-posting
now coming to point about your Question
=SUMIF($G:$G,$A3,H:H)+SUMIF($G:$G,$A3,I:I)
i think the formula should be like this
=SUMIFS($G:$G,$H:$H,$A3)+SUMIFS($G:$G,$I:$I,$A3)
or
=SUMIFS($G:$G,$H:$H,$I:$I,$A3)
Hope it will give some idea about the formula other wise please give some more details and it is better to upload a sample file using with the link: - http://chandoo.org/forums/topic/posting-a-sample-workbook
Hope You Understand
Thanks
