Greetings all. I am trying to use sumif where the range and the sum range
are the same. I want to have one cell, say H1 that displays the sum of all
values in the range H7:H10000 where the value is negative. This is what I
have tried, but I get the error box saying there is something wrong with it.
Is it not possible to have range and sum range the same? And if so how else
could I do what I need to do?

=SUMIF(H7:H10000, < 0, H7:H10000)
