I cant seem to find the answer to this,

If I use "Open URL" to open a file, and the file does NOT exist, is there an error generated? if so where can I find this error? is there a Get function?

If the file does not exist, I'd like to be able to show a custom box that tells the user.

Thanks in advance

If IsEmpty(Your Field)I believe will give you what you want.

I could be wrong, but doesn't FileMaker just pass the URL to whatever mechanism the operating system uses to open them, the web browser? So I don't think there is an error returned. They'd certainly find out in a hurry.

If you really need to know whether a file exists, without even running a script, Troi File can do this, and likely other "file" plug-ins, such as the (cheaper) one Productive Computing has.

AppleScript can do this easily on a Mac, but it requires a script.
