Debugging server-side script can be a challenge. Usually with VBScript, you can use functions, such as msgbox, to determine the status of script variables during debugging. Because server script cannot display user information, you cannot take advantage of such features. To overcome this, Access Workflow Designer provides the Logger object.
The Logger object has two methods, PrintString and PrintObject, that append output to the Workflow Log (modwfe.log) that can be found in the Windows directory on the server. You can use these methods to print out debugging information.
Important Because the modwfe.log file is stored on the server, developers wanting to use the Logger object must have access to the file. The server administrator can share the file or directory to make it possible for you access to the log file. Members of the modAppOwners group do not have permissions to this file by default.
