Hi+ACE-  I typed in a filtered webpage +ACI-http://www.switchboard.com/bin/cgiemail.dll+ACI- 
with checkboxes: first name +ACI-hu+ACI- , last name +ACI-ming+ACI- ,sent back. This is the result page I got. How should I correct the error? What does +ACI-getsize+AD0-3D getpart+AD0-3D+ACI- mean?  There's no file splitting here. Thanks+ACE-
