Hi there. Are you expecting it to add up those rows that have a zero as the last digit? i.e. rows 3,6,10,11,12,14 and 15. If so, you will need to have the numbers converted to text in a helper column first. Use the formula =TEXT(E2,0) in (say) column I, and then use that column for the range, so your formula becomes =SUMIF(I2:I22,"*0",F3:F22)
