returns 1 if a file or directory exists
otherwise 0 will be returned

result_field should be a standard text field of the current table or any global field
at least one record is required in a table to return a value to a global field

there is no way writing a result of an AppleScript directly into a FileMaker variable if using the common FileMaker function "perform AppleScript"

U shall use a standard POSIX path or a common FileMaker paths like:
"filemac:" & Get ( DesktopPath ) & "file.csv"

The script removes prefixes like "filemac:" or the name of the start volume like "/Macintosh HD/" from the path automatically.

Use the ScriptStep "Perform AppleScript" using the option "Calculated AppleScript"
You also shall use "Perform AppleScript" directly from a button.

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

This is my Custom Function and I want to edit it


parameters changed:
a global field for returning the result will be referenced directly
