This section lists the error messages that the version 3.1 Help compiler version 3.1 displays when it encounters problems building a Help file. Whenever possible, the Help compiler displays the name of the file that contains the error, as well as the number used to identify the specific line of the Help project file or the topic that produced the error. Since topics do not contain numbers, the topic number specified in the error message refers to the topic’s sequential order in the topic file. In most cases, the topic number given in the error message will match the topic’s page number in the Word for Windows document.
