I have 3 places on my form where clients of mine area allowed to upload files. I have clients that are sending Pages documents, and I have enabled that as an acceptable file type (see attachment). Why then do I still get the error that says "Please enter a value with a valid extension." when I select a Pages document to be uploaded???

Thanks for your help!!

I think the issue is with .pages extension specifically. I know on a mac, those files are treated kinda like a folder. You might not be able to have those file types to be uploaded.

Thanks, Scott.
I exported the Pages as a Word file and it uploaded without issue.
