excel - Sum first three (or four) non blank cells in a row -


i have box office sheet. it's far more complex this, is:

enter image description here

i want sum first 3 days gross of each film (opening weekend), jumping blank cells. make little more complicated, want add possibility 4 or 5-day opening weekend. there column i'd enter number of days.

i'm familiarized basic functions , few complex ones. possible keep simple?

while try accomplish formula results without array formulas¹, don't know way accomplish without one.

in e4 array formula¹:

=sum(index(f4:l4, 0, match(1,sign(len(f4:l4)),0)):      index(f4:l4, 0, match(1,sign(len(f4:l4)),0)+d4-1))

fill down necessary. iferror functionality wrap around circumstanses # of days , available columns mismatched.

        sum_by_days

¹ array formulas need finalized ctrl+shift+enter↵. once entered first cell correctly, can filled or copied down or right other formula. try , reduce full-column references ranges more closely representing extents of actual data. array formulas chew calculation cycles logarithmically practise narrow referenced ranges minimum. see guidelines , examples of array formulas more information.

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac
