Dear colleague:

It is difficult to reproduce the error for me because:

1) you use probably automatic field naming (no barrier) 2) you use non-ASCII characters (Chinese?) that my machine is not set up to decipher 3) you use "include onytfrm.txt" which was not inlcuded. As it probably contains the Label blocks, it becomes impossible to read the file because none of the CHECKS exists

Regards,

Hans
