Import question from a new user

[Kristen.Billings at med.va.gov]

I am very new to Metacard and have a (hopefully) simple but frustrating
problem. I have been importing images into my programs with no problems on
both Mac and PC using the "import paint from file" command in the message
box, and they appear with no problems on my page. However, when I try to
import quicktime videos using the "import videoClip from file" command on
the PC the program acts like it is importing the clip but the clip doesn't
show up on my page or anywhere, and on the Mac when I do
file-import-videoclip it says it can't open file, mask, or display and when
I use the message box command it gives me an error message. Help!
