i'm sorry because i may be i make you misunderstanding. What i mean is the value of success can't updated in the function defined in the head section. when i initialized the global variable success=0 in the head section and click the link, the value that i printout is still 0 and not 1. Can somebody help me to solve this problem? thanks.

you need to give a value to the var when you initialise it to avoid errors.
the doc.write will not work anyway but try the below - it uses a form to show the success of success! <html> <head> <script> var success=0; function openfile() { success=1; document.one.here.value=success; } </script> </head> <body> <a href="javascript penfile()">Click here</a><script> document.write(success); </script> <form name="one" method="post"> <input type="text" name="here" value="0"> </form> </body> </html> ------------------ Simon Wheeler FirePages -DHTML/PHP/MySQL
