This record cannot be modified in this window because it is already being modified in a different window.

But there are no other windows open. If I open the Data Manager (accept, do not save this record on the way) , and close back out (without doing anything), then it will accept the data.

weird.

any help is appreciated

Sure you don't have any other windows open? Say, with a window position that pushes it off-screen? Check Window menu... -> Show Windows.

Hello,

OK, yes, there are no other open windows accessing this record. There is one other window open but it is just the title page with a link to this layout. The title page is the problem though. After a bit more playing, what allows data to be added is after accepting the "Save changes to this record" prompt comes up before a re-login, data management, etc. Once the "record" has not been saved, it is open. The confusion to me is there are not any records being created on the first page. It is just a title page with links. OK, so what am I looking for and how do I fix it?

thanks

You can not make changes to an inactive window. In other words, the other window has the focus of FileMaker.

Not being able to see your files, I'm guessing what might be behind this, but something has been left undone in the other window. Try a commit record in your script.

Yes, but the layout the title page lives on must be tied to a table occurrence. Which may point to the same base table as the layout in your second window. You may not be creating records here, but you may be opening them, by setting fields etc, and thereby locking them.

What Lee said; either have your scripts that your "link" buttons use perform a Commit Record/Request prior to navigating away from the window, or have your title page layout be tied to a "Null" table occurrence - a base table that serves no other purpose, and is tied to no other TOs.

thanks for the help. Got it.
