Have you used a tool such as fiddler to see what is being returned and sent?

Eric

Is there an error?

Eric

crd = what?

Is that a file input? You can not submit files with an Ajax call.

Eric

onclick="delcat(this.form)"

{
var iObj = new Image();

location.reload( true );

Eric

Why the full page refresh?
