By "stored externally" do you mean the new external storage option in FileMaker 12?
or do you mean storing a file "by reference"?
Drag and drop embeds the file in the container you drag to so I'm not clear on how you are using fields to specify a file path since the file is not stored by reference in the field when you drag and drop into it.
Perhaps there are more details about what you are trying to do that you can share with us?
Yes, im using FM12 external storage option. The field names don't come from the file, they would come from elsewhere in my database.
Are the fields defined in the same table as the container field?
Are they fields with global storage?
Clicking specify on the storage tab in field options opens up the standard specify calculation dialog so it looks like what you have specified would work if you wrote the expression like this (assuming three fields with global storage specified):
"Tutorials/container/" & Globals::field1 & "/" & Globals::field2 & "/" & Globals::Field3 & "/"
But I haven't tested that option to see if it actually works as expected...
The fields are in the same table as the container field
Does that mean that you are specifying a different location for every file placed into the container?
are you using syntax like what I posted?
Yes, different location for each file. I have it working now. Used your syntax except didn't need the globals:: Thank you!
