Caleb Ruth, Data Performance LLC

A recursive function that returns a 1 if a value is found in the supplied list

Sample Input:
ValueExists ( "rabbit" ; "mouse¶rabbit¶lynx¶snake" )
Sample Output:
1


 Then copy & paste into FileMaker Advanced's Edit Custom Function window.

Description:

The same results can be had using the native FilterValues function, but I find this to be more logical. Recursion limits apply to the size of the list.

Note: these functions are not guaranteed or supported by BrianDunning.com. Please contact the individual developer with any questions or problems.

This is my Custom Function and I want to edit it

More intuitive 2nd parameter name than above. ValueExists ( valueList ; value ) :

GetAsBoolean (Position ( ¶ & valueList & ¶ ; ¶ & value & ¶ ; 1 ; 1 ) )

GetAsBoolean (Position ( ¶ & valueList & ¶ ; ¶ & value & ¶ ; 1 ; 1 ) )
returns 1 when valuelist is "123" and value is "2"
beware of that.

Edit:
GetAsBoolean (Position (valueList; value ; 1 ; 1 ) )
returns 1 when valuelist is "123" and value is "2"
beware of that.
