Did You save the CF's? I'm asking this because there is a problem with the user interface (different paradigm): One hit of the esc key - and all edits are gone... without any trace..
CF's appear here all the time - therefore the principal should be fine. Any chance that there are several files?
I can edit CF's I create, so Filemaker knows they are there. but they do not show up under Custom Functions in Manage Scripts. I do not know how to save a CF, other than click OK in Edit Custom Function window (and the availability is set to All Accounts).
And yes, there are several FM files on our server, but what does that matter? The problem is within one file. I'm not trying to access the CF from a different file.
I don't use CF's that often, but I never had trouble in v12.
Thank you for your posts.
Create a new database file and create a new custom function. Then, create a Calculation field, click on "Custom Functions" and see if it appears. If this doesn't work, then there is an issue with FileMaker Pro, and I would recommend reinstalling. If this does work with a new file, then go to the last backup of file in question and see if you are able to replicate the issue. If the backup has the same issue, try recovering the backup file, open the recovered file, and try again.
Keep me updated with any progress.
