Sum values based on multiple criteria

[Jorrg1]

Hi

I would really appriciate if I could get some help with this dilemma.

In the yellow cell I want a formula that can sum up all the numbers in row D, based on which account numbers I choose in the box in row J. They have to be linked to the account number in row C.
So since I already have choosen the numbers 4000 and 4050, the amount in the yellow cell should be 47275.

I also have to be able to change the numbers in the box to get new results as I please. I need to be able to choose account numbers and automatically get new answers in the yellow cell.

Thank you!
