Thank you. Did not know quotes were not required around return character, although that does not affect functionality. Custom function works; corrected sample data.

An array is assumed to be a value list. A return character added to the end is not necessary unless to account for an error if the array is malformed. Passing a value as the second parameter instead of text circumvents this error handling, however.

Great custom function.

I tried the following scenario:

Let (
array = "30300¶303¶408" ;
value = "303"
cfFindInList ( array ; value )


Another scenario:

Let (
array = "30300¶303¶408" ;
value = "30"
cfFindInList ( array ; value )


Correct result, ´cause the ( exact ) value 30 is NOT part of the array.

The custom functions returns a value greater than 0 only if the exact value is in the array.
This is exactly what this custom function does.

Awesome. Thanks to the developer.

In my program I add the prefix "cf" to all custom functions.

Thanks, Ben. I have been using ƒ to denote custom functions for the last couple years.
