I am trying to allow people to attach a pptx file

I have updated my form to allow a .pptx file to be added, but it's not working. I keep getting this message (see screenshot). I've updated it in options so it now has this list of extensions:

pdf, doc, docx, xls, xlsx, csv, txt, rtf, html, zip, mp3, wma, mpg, flv, avi, jpg, jpeg, png, gif, pptx,

Please let me know what I need to do in order to allow people to attach these files.

Many thanks

Nancy

Hi,

In your file upload properties, can you please remove the comma after pptx? That causes the problem, last item should not end with comma.

Hope this helps,

Thank you

Thanks that worked!!
