I would suggest that you comment out the offending command and re-enter it from the keyboard. It appears that the command is failing the syntax check in the command. I have not checked the vars package but it is usual to do a syntax check before the data is analysed. you could also have a look at your script in a hex editor.
If this does not solve your problem I would suggest that you send to the list your script and data in text format as attachments.
