Detecting if a field is defined in VBScript?

[#1]

I'm trying to detect if a field is defined in a document in a VBScript macro but I don't see any obvious predicate or test to do so.

For example, if I retrieve a field like this:

set kaboom = ActiveDocument.Fields("DOESNOTEXIST")

Then kaboom is not null, is not empty and is an object.

So would do I test if ActiveDocument.Fields returns a real field in the document?

Thanks,

Maybe you can use the system field $Field.

Yes, that looks like it will do the trick.

Thanks!
