Look up and sequence multiple values

[Macky70]

Hi Folks,

New to the site ...thanks so much for all the contributions.

I have a (race/lap) spreadsheet that has the following (Note: square brackets [text] are to isolate examples and not in the actual formulas) :

- Sheet 1 (Registration): Manually entered race number (Plate #; Column B), racer info (name, etc) and Number of Laps pulled from "Laps" sheet [=SUMIF(Laps!B7:B500,'Registration List'!B6,Laps!C7:C500)] and Total Race time pulled from race sheet [{=MAX(IF(Laps!B7:B500='Registration List'!B6,Laps!E7:E500))}]

- Sheet 2 (Laps): Enter initial value (0) in "B7" to start race time [=IF(B7<>"",IF(D7="",NOW(),D7),"")]; and manually enter Racer "Plate #" (Column B) each time racer crosses the line; formula collects the "lap" [=IF(B8<>"",IF(D8="",NOW(),D8),"")] and associated times [=IF(B7<>"",IF(D7="",NOW(),D7),"")] and elapsed race time [=IF(D8<>"",D8-$D$7,"")]

- Total laps are "counted" and displayed next to racer's info and racer's last (MAX) time is pulled into the "Registration" sheet to show racer's Total race time (see above)

Ideally, I would like to pull the individual lap times for each racer as well, but this is where I start to get lost ...

Plate # may occur multiple times in Column B w' associated lap times ... I'd like to isolate the Plate #s (e.g., 41) and pull out the elapsed time for EACH lap. More specifically:

Start time: 12:00
Plate #41:
Lap 1 (12:30:00) ... 00:30:00
Lap 2 (13:01:02) ... 00:31:02
Lap 3 (13:33:05) ... 00:32:03
... etc for each racer

Hope I provided enough information ... looking forward to your thoughts. Thanks in advance.

Attach a sample workbook (not image).

Make sure there is just enough data to demonstrate your need. Include a BEFORE sheet and an AFTER sheet in the workbook if needed to show the process you're trying to complete or automate.

Make sure your desired results are shown, mock them up manually if necessary.

Remember to desensitize the data.

Click on GO ADVANCED and then scroll down to Manage Attachments to open the upload window.

Attached (updated) SAMPLE spreadsheet w' desired results ... thanks

See Sheet1

in B1

=Laps!D7

in B5

=IFERROR(INDEX(Laps!$D$8:$D$1000,SMALL(IF(Laps!$B$8:$B$1000=$B$3,ROW(Laps!$D$8:$D$1000)-ROW($D$8)+1,""),ROWS($D$8:D8))),"")

...confirmed by pressing CTRL+SHIFT+ENTER to activate the array, not just ENTER. You will know the array is active when you see curly braces { } appear around your formula. If you do not CTRL+SHIFT+ENTER you will get an error or a clearly incorrect answer.

Copy down

in C5

=IFERROR(B5-B1,"")

in C6

=IFERROR(B6-B5,"")

Copy down

There is no check for lap nos: assumption is times are in lap "sequence"

Seems to work - thanks so much!
