Hi, Thanks for answering the question.
I'm going to make it write to a database rather than text file after searching google and coming accross common problems with text files. I've now just got to figure out how to mark the message as read in the database so it does not re-appear next time the user clicks update. I'm going to build a function that will put the message in the correct table using an if clause, is that the best method?
