# Thread: Sum using right or left function Thanks: 0 Likes: 0

1. ## Sum using right or left function

I have a simple attendance tracking spreadsheet. Data validation is set up to select the "violation" from a list. The violation also has a point total attached to it. Example: Call off 1.0, Early out 0.5, NCNS 3.0, etc. How can I sum a range using the "Right" function? I'm only interested in the values 1.0, 0.5, 3.0 etc.

I can get it to calculate if I do each cell individually:
=SUM(RIGHT(C3,3),RIGHT(D3,3),RIGHT(E3,3))

How can I simply highlight the entire date range and use the RIGHT function to calculate the point values? (Columns C-E)

 Name Total Points 8/2/19 8/3/19 8/4/19 Bill 3.00 Early Out 0.5 Absent 1.0 NCNS 1.5 Cathy 1.00 Excused 0.0 Early Out 0.5 Early Out 0.5 Sally 1.50 Tardy 0.5 Tardy 0.5 Tardy 0.5 John 2.00 Vacation 0.0 Absent 1.0 > 50% shift worked 1.0

=SUMPRODUCT(--(RIGHT(C2:E2,3)))

Try:

=SUMPRODUCT(--RIGHT(C3:E3,3))

PS.... Just saw Fluff's similar response. There is no need for, nor benefit to, putting an extra set of parentheses around RIGHT(C3:E3,3).

Works perfectly! Thank you both.

Need help with one more thing. I've modified your formula a bit. It works as expected with one exception...I need to include something that will avoid throwing an error if there's a blank cell in the range. I've tried a few different things all producing different results. Just to clarify the blank cell would be in E3:NX3.

=SUMPRODUCT(--(INT(\$E\$2:\$NX\$2>TODAY()-365)),--(RIGHT(E3:NX3,3)))
