Hi @momureithi ,
Put this on the OnAddFile of the Attachment Control
If( Right( Last(Self.Attachments).Name, 3 ) <> "pdf", Notify( "You can only attach PDF files", NotificationType.Error ); Reset(Self) )

You just need to add them

<> "pdf" || <> "doc" || <> "xls"

Hi Warren - what would your suggestion be for:
pfd, xls, xlsx, doc, docx,
So allowing for the 3 & 4 digit file extensions.

Ok - I thought
Last(Self.Attachments).Name, 3 ) <> "pdf",
was looking at the last 3 of the file extension, for example i was thinking it would see: pfd, xls, lsx, doc, ocx, instead of pfd, xls, xlsx, doc, docx,

@AdamH ,

No, it is looking at the last 3 characters - you can actually do this another way - just keep adding them.

If( !( Lower( Last( Split( Last(Self.Attachments).Name, "." ) ).Value in ["pdf", "docx", "xlsx"] )), Reset(Self); Notify( "Only pdf, Word and Excel files allowed", NotificationType.Error, 5000 ) )
