Help:VE30
From TrainzOnline
The tag tagname in containername refers to a nonexistent file: filename.
The container includes a tag that requires a filename as a value. The value used for the tag refers to a file that could not be found. It may be misspelled, it may be missing, or it may be located in a different folder.
For example, for a config.txt file that includes a thumbnails container:
thumbnails { 0 { image "$screnshot$.jpg" width 240 height 180 } }
the error message is: - VE30: The tag 'image' in '0' refers to a nonexistent file: '$screnshot$.jpg'.
The required fix is to change the filename to the correct name of the image file: '$screenshot$.jpg'.
