Dear Hans, Thank you for your reply.
I have tested using "JS(Set_Field{FFD2,1})" before, but it didn't work. I have tried once more. But it is same before.(After click "restart", I have a blank window and nothing happens when I click "here" again.) If it works in your machine, that is the problem of my macbook. I am using Macbook and OSX 10.6. Thank you again. Best regards, Dalyoung ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________
