This seems like it should be simple but after googling for hours and trying many different approaches I'm stumped.
I have a table of values containing single and two digit numbers, and a cell containing the list of values to be counted. This list of values is separated by spaces and can be any length.
The first version of this I did worked fine because I was only using single digit numbers in the table. This is the formula I used: =countIf(arrayFormula(regexMatch(<table>, substitute(<cell>, "", "|"))), TRUE)
So in my list cell I can put 2 4 6 and all the cells containing those numbers will be counted.
For the second version I need to able to put 3 12 and make sure values like 2 and 13 would not be counted.
I would like to avoid using VBA since I want this to work in sheets, number, excel, etc.
