Export text file from corel sript?!

Will somebody help me?
When I use function FileExport for text exporting from cdr file
I get this message "Error: filter does not support specified bit depth"
Problem is in parameters for xresolution and yresolution in this function.
It seems that the function is only for bitmaps and vector files. Do anyone
knows whith are the right values for these parameters?

Function FileExport(ByVal FileName As String, ByVal FilterId As Long, ByVal Width As Long, ByVal Height As Long, ByVal XResolution As Long, ByVal YResolution As Long, ByVal ImageType As Long, ByVal AntiAliasing As Long, ByVal Overwrite As Boolean, ByVal SelectionOnly As Boolean) As Long
