Subtract a numeric value from the last populated numeric cell in a colum if another cell has a text

[AJMack82]

In the attached time sheet, I am trying to work a formula that will subtract the numeric value of Column B from the last numeric Value in column I where column H as "H" populated.

=IF(H3="H",$L$7-B3,"") brings the initial value for my calculations forward if "H" is in column H. The challenge is to use the latest value in Column I as the number to be subtracted from

@AJMack82 , that could be

=IF($H4="H",$I$3-SUMIF($H$4:$H4,"H",$B$4:B4),"")

or even better

=IF($H4="H",$I$3-SUMIF($H$4:$H4,"H",$B$4:B4),0)

with custom format [h]:mm;;

This looks fantastic thank you. Now just to try and understand how it works :)

@AJMack82 , you are welcome. For the current row if in I is "H" you sum values in column B starting from $H$4 till current row if only in column I for the same rows you have "H" and subtract result from $I$3.
