5. The custom function you copied appears at the bottom of the list. If FileMaker Pro determines this function is invalid in the context of the target file (for example, a dependent function, field, or calculation is missing from the target file or the function contains an invalid field type reference), the pasted function is enclosed in comment characters (/*<function_definition>*/). For more information, see Custom Function dependency rules (FileMaker Pro Advanced).
7. Click OK.
• To change the way functions are sorted in the Edit Custom Function dialog box, choose a category from the View list.
• The content of a custom function is protected even if it is set to be available to all users with Full Access privileges. To edit or view the custom function content, you must have Full Access privileges and be editing the database in FileMaker Pro Advanced.
• When a custom function is deleted, it is no longer available for use. Calculations that were using it will return an error when they attempt to call it. If you have Full Access privileges to a database and are editing a calculation that uses a deleted custom function, the name of the function is replaced with the string <Function Missing>.
• If you do not have Full Access privileges and attempt to edit a calculation that uses a custom function restricted to Full Access accounts, you see the string <Private Function> instead of the custom function. You cannot change the calculation as long as the <Private Function> declaration appears in the formula.
• If you have previously created custom functions and the names are identical to new FileMaker software functions, the FileMaker functions will override your custom functions. Verify your custom function names against the FileMaker functions, and change your custom function names if needed.
• The characters $ and } can no longer be used in a custom function name or a parameter name. If you used these characters in custom function or parameter names in FileMaker Developer, you must rename them in FileMaker Pro Advanced.
