NO, no, that is not my issue. Trust me, I know how to get the files sizes allowed.

What I want is a page that displays an error saying that the file is too large when they try to upload a file larger than the alloted 100M (which is the limit for my sites, even though my host has 200M by default).

I only allow 100M sized videos on my site. Person tries to upload video 110M...they get "server connection error". It doesn't tell them that the file they tried to upload is too big. I need an error page telling them that they exceeded the file size upload...something along the lines of a file status...'We're sorry but your video file is too large, please reduce the size to 100M or less and try again"...something like that.
