Use On Error Resume Next for debugging purposes and the Response object to output messages directly to the page. (Response.Write) Also use the Err object to check for errors. (err.number, err.description, etc.)

Once you've got things working you can remove debugging code.

>The problems are that in this function some vb commands are not correct or are not executed and i can use Application variables from file global.asa. If i exclude all the commands and leave only the window.close command the function is executed so the problem is in the syntax i use.
>Someone can help me ? i have to save data and i need to understand which kind of commands to use and how can access the variables stored in global.asa and the difference between source in sub function and that in <% at the top of my asp page when i open the table and run a query.
